7th Gen (2001-2005) Honda Civic DIY - Repair Your Rear Power Lock and Window Wiring Harness 

Thank you for posting this video, I had replaced my lock actuator but it didn't help (returned it to amazon), so I watched this again, and sure enough, the wires were damaged and split! Took it out, cleaned them, soldered them and put it all back together, my 15 year old civic now has its rear door lock working again, and it didn't cost me a penny!

Thanks for this video! My JDM Honda Fit's rear right door isn't locking/unlocking, and I've determined it's a broken wire. Knowing that there's a connector inside the door pillar and how to pull out the door wiring harness should make the next stage a lot easier.

I really appreciate how detailed, thorough and careful this video is. Although I'm not replacing my harness yet, I know I could after watching this. My daughter's car window was stuck down and using the information from this I was able to jiggle the connector boot between the door and frame to get it rolled up. Really appreciate your work here.

Just fixed my wiring harness! We take the little things for granted, like your rear door automatically locking. Thank you for your video!

Great job, descriptive steps and best of all, everything works! I am enjoying your Civic repair videos - thanks!

Awesome lesson. I have the same daunting problem with my front passenger side power window. I thought it was the window regulator motor. Purchased a window regulator but when I removed the door covering, I tested the power to the window regulator but there was no voltage. Then I checked the Honda manual and found that each of the four doors has a fuse. When I checked the fuse for the passenger side power window, it was blown. Voila! Thought I had my problem solved but when I purchased 5 - 20A fuses, I switched power on and one fused blew immediately. Then I disconnected the harness cable for the window regulator and connected it to the newly purchased regulator and another fuse was blown immediately. Now I know it is not the window regulator. Is it just a coincidence that the other 3 door windows work but the one on the front passenger side does not work. I knew that I had a wiring problem somewhere. This RU-vid video shows me with a 99 percent degree of confidence where the electrical short is located. The only problem is that the harness boot is on the front driver's side instead of the rear door. Hopefully, I will be able to remove the rubber boot from the front with a little more effort than what is shown in the video. At least, after viewing this video, I know where the problem is located.

Thank you so much for this video! My window was never working but now it will be with this!!! Thank you, you saved me so much money!!!

I just wanted to thank you for making this video! On my civic the driver's side rear door window and power lock both were not working either and with this video I was able to find and repair both broken wires quickly. Cheers...!! Ian

This video is as good as it gets. Well articulated and photographed with adequate details at all steps. Thanks.

Really helpful video. Gave me the confidence to fix the problems I'm having with my 2002 Honda Civic. Seeing how it's done is so much better than just reading about it. Thanks.

This video helped tremendously:). I just bought a 2003 Acura 1.7EL, for a winter car/work commuter. On my way home, I noticed the rear windows were not going done, so I kept playing with them, until the RR window went down a couple inches, then I couldn't get it back up. I googled searched and found your video. My wires wernt as crinkled up as yours, so I just straightened them out, then the window went up fine, and now works. The LR window doesnt work either, so I will give that a shot also. I'm just happy i got it up, and really never need to use them, but at least i know how to fix them. Thanks again.

My wiring had good continuity even though one wire had 2 small breaks in the insulation that I taped up. I had a bad connection in the plug that connects to the window motor. I bent the prongs slightly and got a good connection. Window works again. Adding this comment in case your wiring appears OK but same symptom. Great video which was a great help disassembling the door.

Great!! This gives me the confidence to tackle the issue myself on my 2005 civic. The dealership wants to charge me an arm and a leg! Thanks for the vid!!!!

This was really well done. Thanks for taking the time to make this video!

Appreciate the time, detail and efficiency demonstrated in this video. I don't think it could be better. I have purchased a driver's side master switch new...twice. And the rear windows still won't work, although they do go up directly from the rear switches. I doubt that 2 new switches could be faulty, so believe that it must be related to the wiring somehow. A compromise between the rear windows and the master switch may be the culprit, and this video was comprehensive enough to make me feel confident to investigate. It is not viable to pay a shop for something like this, as the time and rate billed would be considerable. Thank you!

Great video on how to fix the door lock and power window. Thanks for your time in doing this!

Very detailed information, clear, and understandable.thank you so much

This can apply to other Honda Acura models in the same year sequence. Found your purposeful intentional descriptions and comfort with silence refreshing.

thank you so much my rear driver side door lock stopped working today this helped so much!!!

Appreciate your care in filming and lighting here. I'm a total novice and this makes perfect sense to me.

Excellent video instruction and I think it will solve the problem I've had with my '02 Civic EX Sedan. Thank you!

One of the best repair videos I have seen Thanks

Great video I wish all repair vids were this good

Really a fantastic video. I had the same problem but this is the drivers rear power window. I did exactly as show on your video . I found that one wire is broken. But i solder all the wires .Thanks a lot for the video. I found out the cost of wire harness is around 35$ .

Great video (as usual)! I have this same issue on my 2001 Civic LX (Driver's Side Rear Locks) so now I know how to fix it... if I want to go through all the trouble, that is!

Showed all steps clearly. Great vedio as always.

Thank you for the video! This was a lifesaver.

very useful, i learned some stuff about soldering wires... thanks.

This has ever been a fit with power windows and locks since they first started adding creature comforts. I just found one of my rear doors is acting the same way, with both the locks and windows not functioning. Pretty sure its the same problem in the harness. Appreciate all your help, and feel certain your outlined repair will solve my ill as well. Best wishes.

Excellent video. Thank you.

This is sooo useful my front passenger side door on my 2002 civic lost power completely im definitely going to try this!

very good video and nice explanation, i will try to repair my self now thanks

Dealer want $465 to replace the wiring harness! You saved me. Thanks!

Should I replace the switch and check? Because when I check through electric jumpers my window went up but with the switch it's not moving

Thanks so much. Very helpful!

Excellent video

Great video! Thank you!

Well done! Is the first video I am watching no offense with all the process congrats

Great video,I have the same car with same problem with both rare windows and after watching this video I have opened it and not sure I ll make it or no 😓

Fantastic video, thanks

Thank you, helpful

Beautiful thanks for your video, I have the same problem,.good job ,.thanks

thank you for the help 😃

Thanks a lot !!!

It will happen to you also just a matter of time but this is a great video to fix it up right .

Great job bought a 2001 honda HRV 1.6 vtec last week rear windows both sides not work from front or back also one door rear left not open from inside or outside what you think wrong please? Also have panel on worst door almost off but metal rod to handle with plastic cover still conect to handle dont want break but keeping from removing panel completely off any ideas how it come off?

Looks great. My car has the same problem except it is the driver side back door. I am sure it is the same culprit. I’ll come back once I fix the problem.

Good video.

Great 👍🏼 thanks 🙏🏼

Could you kindly let me know the wire size in door harness for Hond CR-V 1997 (RD1)? Thanks,

THANK YOU VERY MUCH

My 2001 civic blows fuses on the passenger front and the left front speaker that quit working is the harness too short and then wears through the insulation and then shorts to ground ?? good video '

Thanks for reply,actually I got that whole bunch of electric cable part from junk yard I repleced it and checked the motor before doing that so motor is fine coz window was moving using the electric jumper but after installing this new cable my window is still not moving pls recommend where else problem would be I will really appreciate the help

Pierce... Question... The foam piece at 4:15 at the bottom of the door, what's its sole purpose? Mine was loose and was preventing my window from going all the way down. I didn't have any "goo" to re-attach it so just left it off. Thanks

I have a 2003 Civic 4 Dr EU8 model with passenger and rear passenger door power lock problems. Any chance you could do a video on that model ? The front door wire harness looks harder to get access to

Thanks for uploading this. In the process of removing the rubber door boot that protects the wiring on the rear driver side door, I found that the wire that connects to the rear wire harness, coming out of the front/middle compartment of the door, has almost no slack. There's so little slack that I worry in the process of placing a replacement wire harness (due to extensive fraying / severed wires within the rubber boot), I might damage the connector. Any clues as to how to find and perhaps feed more of that connector from the front/interior door so that it isn't so precariously tight?

thank you so much (Obrigado) in Portuguese language.

And do you think it's the problem with the fuse if yes pls let me know which one is the fuse for rare window in the fuse box, thanks

When i removed my quarter window. One of the washers fell inside the car door. I was removing the bolt that holds the long piece that divides the big window and quarter window. Where does that washer go? Does it go directly behind the door frame? I have a honda civic 2003. Thanks.

good video. many thanks. if this door only does not respond does it mean harness got cut ?

I am installing a car alarm and need a wiring diagram for lock and unlock driver's side. I have honda civic 02 vii ep .. I found some info but it is for civic vii ep3 idk if it is ok... please help !

Eyvallah

I just removed the rear passenger side harness and to my surprise the wires are perfectly fine

This is awesome! Looking forward to trying this on my 02 Civic LX. Do you think this trick would also work on the passenger front door? I have the same problem there...

Thank you

Very interesting! Unlike the wires, which you have pointed out, most people will usually point to the actual lock and window motors. I'm having issues with my right side passenger door. The window will fail in extreme cold, and the lock doesn't always lock properly. I'm aiming to change the actual motors and not the wires. How often are the wires to blame?

You are right fuse r fine motor is working properly electric cables r also good now I have been told by a machanic it's the problem with Programming which only Honda dealer can fix it 🙄

I couldn't figure out how to remove the plug that goes into the far right inside the door. I'm working on the front passenger side. It looks like the grey connector on the end of yours and you said to use needle nose pliers

Nice video! Can you tell me what wire wauge you're using?

can I just cut the 90 degree rubber area with a slit and take flash light to see of the wires are disconnected? just trying to avoid 6aking the door apart..

hey... I appreciate the vids on the 7th gen honda civic. I have a 2005 LX coupe with about 93,000 miles on it. I'm thinking the heater hoses are about due for replacement, but I can't seem to find any videos for that repair. If you have done that on your civic, can you give me any tips? or, if you're planning a video, I'll wait. Thanks.

Would simply wrapping each wire with electrical tape have solved the symptoms since the conductors themselves were still intact? Thanks for the great video! We're still hanging on to the '03 Civic with help from posters like you.

So I ended up replacing both my rear passenger side harness and the window regulator. Still didn't work until I reconnected the window switch for that door. That worked, and my driver's side switch started working after that. Pretty weird. The funny thing is I've had problems for so long that both my harness AND the window regulator were both bad. I tried swapping back in each of the old parts and the window stopped working again. So it is possible to have both go bad after 20 years. I actually think the harness went bad many years ago. It just started working randomly like a year later. Then the regulator went bad maybe because my master switch has sticking buttons maybe burned the motor out.

Great video, this method could apply to a 8th gen civic coupe driver side too?

Nice!

Thanks! This was the problem exactly. I had three out of the five wires completely severed. The weird thing was, where the breaks were, there was e-tape over the wires. We had never been in that boot (my wife is the original owner). Has anyone else found factory flaws repaired in the doors?

Do you need a specific wire gauge @ 13:33? I need to purchase some

Can some one please give me a tip? I have 01 em2 my passager window just goes down but not moving up back. My central locks work fine just this stupid window

where can I buy a brand new wiring harness? thanks

piercedasian. Do you know if the rear door for an Accord is very different ?

How do you test if the harness is what's broken and not the motor?

I jsut got a Civic 2001, its looks quite okay for such an old car. I noticed that only my driver lcok and tail lock open. Is that normal. I believe i got the Coupe model though i got 4 doors and a hatch. I thought hatchback had bigger trunk. Not sure what type it is then haha. EDIT seems its a hatchback model. I need to figure out if this locking behavior is normal.

I changed both left side actuators and my locks still don’t work, my bast bet is digging into the wires?

This problem just won't end. I replaced the harness and the regulator, and everything works great now, except when I put the door panel back on the door lock doesn't move up and down easily. Moves fine without the panel on, but I dunno. Maybe it needs perfect alignment or something, I've been trying to get it back on for like an hour. Edit: Okay took me like another half hour, but I think it's because I didn't fasten clip of the wire that connects to the window button to the door and it may have gotten in the way of the mechanism or something. Now everything works, except I get slight thunk sound when the window gets fully closed. I don't really care about that though. This window only gets opened like 3-4 times a year at most. But I learned a lot from this experience. That Hondas are very picky about how re-assembly and that you have to put back everything the way it is.

Shouldn't this be a recall like the srs air bags. But thanks for the info. Of course I have 2 vtec's 01 ex and a 02 special edition. Well the 02 was totaled after I spent 2k on and now sueing for damages. And put alot of work into because my mom passed away in my sisters silver 05 civic so that's why I'm wanting to fix everything. I bought the 01 for 500 and no start so I have all the parts to replace everything. But wow what alot of work but it's worth it for me because my mom. I have never greived but the day she passed to be with our true father(GOD)!

Can you do this with the window down ??? It is stuck down

Just subbed!! Do you live in Canada buddy?

sending you a private email Lol, had to replace mine, front door of my Camry girl :-)

PS isnt it better to cut even lengths for the extension so they all the same. I had the feeling you were free-balling here. Or doesn't that really matter? One thing you didn't mention but seems obvious, that wire which was still good also needs to be extended.

I think maybe you should note - for all the rookies or novices, which would be about 98% of us - that BEFORE you tear all the wiring harness apart, that you have ALREADY tested and determined that it is NOT the lock actuator or window motor that is bad.

Im malaysian..i use honda civic 1.7

I guess i need to find that pry tool, didn't seemed very basic to me hahaha

My rear passenger side window doesn't do anything anymore. I don't hear the motor, I changed the driver's side master switch. But the power lock does work. It's annoying because it's only open like an inch, with half an inch exposed from the outside, so when it rains hard I get a little water inside. Sucks cuz I only open that window like twice a year. It actually stopped working for like a couple of years and started working again on it's own one day. After that I tried to open it every now and then until it stopped. Longer story of the day it happened but I dunno if it's completely relevant or if anyone cares.

Nothing to do with my question?

Great video. Thank you.
