Chevy Tahoe Rear Wiper Repair - Troubleshooting and Wiper Motor Removal 

Well, after fixing that broken orange 12V wire, the wiper decided to act sporadically. I added the ground link from the wiper motor mount to the latch mount. That 'worked' for a day, then the motor acted up again. Conducted endless ohm and voltage checks on all the wires in the harness. In conclusion, it was the connector to the motor. The female terminals inside the connector had become wide/loose over 15 years (go figure). Fixed/pinched the terminals inside the connector and it now works like a champ. (In spite of watching Mr. 741 take apart the motor and resolder it and concluding that did nothing, I did the same thing. Good practice though!). Thanks for the excellent video.

Thank you. These vehicles last forever and I'm rather attached to my 2005 Tahoe. Unfortunately, I accidentally left the hatch open while backing into my garage and knocked the wiper parking ramp off. Your video really helped me repair it properly. Thanks for posting!

Very informative video. There are still people that prefer to fix things instead of throwing if away & buying new . UPDATE: I did the repair , it was a very easy quick fix that anyone can do. Just take your time. I wish that I would have found this video sooner. My wife was SOOO happy to have it fixed. Thanks again for the informative video.

Best auto door opener ever!

You have exactly the same Tahoe down to the color as I do with exactly the same problems I have! Subbed! Thanks for sharing!

Great video, I own a 2003 Sierra Model 1500 truck. Love it because it was cheap and just celebrating a 14 year birthday and hitting 150,000 miles look forward to more miles in the future. It has the all-cast iron V6. Thumbs up!

Hey this worked, mine was all gummed up. Didn't even have to unsolder I just bent that out of the way gently thank you

I found that the large orange wire in the harness to the wiper motor had zero volts. After reading other forums, found the recommendation to check inside the 'loom' harness on the top of the hatch. Sure enough, the orange wire had simply snapped, therefore providing no voltage all the way to the wiper motor harness. Spliced it together, and the rear wiper motor works again just fine.

I'm jealous at how clean this car is. I don't think I want to mess with taking the motor out. Most likely my issue. I'm good without. Great video! I wrote down all the steps just in case! Thank you! 😁

I'm painting an old tahoe for my local art car parade. I needed to figure out how to get the rear wiper off since it's just in my way. This helped! thanks! lol

Most common issue of that year with no wipers and defrost is burnt ground at connector 901. Upper right

What an awesome video. So thorough and the explanations were great. Overall, just well done

I just fixed the rear wiper and defogger on my 2003 Tahoe. It was a bad ground in the rear connector for the tail gate. I just wired around it and now everything works great. It helps that I was a Tech and have a degree in Electrical Engineering. This might be your problem also.

Excellent videos! Thanks for the detailed information.

Great video man, it’s very difficult to find any videos that have information on troubleshooting the rear wiper motor. I’m going through the same thing right now. My 15 amp fuse originally blew on the wiper motor and I replaced it with an ATM 15 amp fuse instead of the low profile mini fuse that was originally in it. It was definitely a little too big for that fuse box but I did manage to get the fuse box cover back on it after and It did work for a couple weeks with the new fuse, despite the obvious size difference (still same 15 amperage though). but my wiper stopped working again a couple days ago in mid motion on the highway during a rain storm. but the fuse didn’t blow this time! I was told it could either be wiring or the motor itself. I am going to take back trim off and do a multimeter test on the motor. And I did watch all 3 of your videos.. I noticed it ended up being a faulty ground wire, so I bought a jumper wire to test that after watching your video just in case. Do I need to take the negative contact off the battery when I’m tinkering with the wiper motor? I know it sounds like a silly question but I would feel worse not asking you. Again, thanks so much for taking the time to inform all of us!

Curious as to how you fixed your defroster not working? I also have 12v power to mine but they don’t heat up. Thanks

I use to like my part-time job, it kept me from going nuts at my full-time. lol

This video reminds me I have to do the same thing to my Expedition

I love the camo tape comment. Great video thanks

It's always the little things that give the most trouble.

I removed the windshield wiper assembly from a 2011 GMC Yukon. What I found after the removal is the spline is larger than pictures and video show. My new assembly will not fit over the spline. Has anyone seen this or have a remedy.

Thanks: Great video, think I'll skip trying to repair the motor but now I know how to get the cretin out thinks I'll replace it. I'll get my buddy to do the hard part so he will get blamed if the paint gets scratched. Its my wife's Denali...😅😂

My sister got a 2008 Tahoe with the rear wiper cut off. Do you know if this is typical vandalism or just easily broken?

I didn’t get 12 volts on both legs of my fuse in the truck next to the steering wheel. What would be your next approach? Thanks for your help

So I have a problem with the connection to the battery and the fuse on both rear wiper and rear defogger do you have a video or explain to me how I can fix this please?

Be interesting to see what's going on inside.

Replaced my rear wiper motor on 2004 gmc Yukon Denali and didn’t work. Checked wires a pink wire has no juice 3 of the 4 do 🤷‍♂️🤷‍♂️🤷‍♂️

Having the same issue on my 2004 Tahoe. Removed the motor to find a large amount of corrosion. Took it all apart, cleaned it up..hooked it to a 12v battery and the motor worked fine. Reinstalled it, It came on for a brief second and turned then went off so it still wouldn't work. Tried to jump the ground like you did, still don't work...checked the under hood fuse and the side of the dash fuse, all are good and getting 12v. When I hooked my multimeter to the orange wire on the harness it only read about 10.45-10.60 volts..thinking the orange wire is getting a poor connection somewhere so have to follow the harness to see If the orange wire could be damaged. If you have any other suggestions it could be let me know please.

where did you find that plastic nut did you replace it?

I apologise if this is rude, but are you really short or is your Tahoe really high up?

I just replaced wiper motor and still doesn’t work. I do hear a noise from around motor when wiper switch on. Fluid pump does work

So one need to make a video on rear hatch wiper motor and I have two trailblazers and 1 works so I placed in on my nicer trailblazer and I now not working on it but works on my nasty looking one so what's the priblem

My 03 just doesn't spray. It works and so does defroster and there's fluid in the reservoir.

Green is always the ground

@sevenfortyone my 05 has that white paint on wiper arm as well and I've seen it on other Tahoes, any idea how the paint gets there?

Would you have any videos on antifreeze reservoir leaks 🤔

Where is the link?

Has anyone had an issue with the rear wiper moving when you use the left turn signal? I replaced the wiper motor, the turn signal switch and the dimmer switch. Items Replaced: goo.gl/QqRn2u goo.gl/f4uWsM goo.gl/y4crB1 I can't figure out what cause the rear wiper to move when I use the left turn signal. I removed the dimmer switch so it would stop the rear wiper. But that's not a long term solution. Any one have an idea?

It looks like you completely skipped over the part where you remove the motor from the inside and outside

don't assume that ALL people know what you're talking about..wish those who post these videos would watch them before posting... DON'T use your finger to point at what you are talking about... use a pencil ... make sure we can see everything you are talking about..(ex...like the fuse you say is out of our view,and trust me it's there ??????) hand is in the way while testing/using meter....can't see how you are doing it... one nice thing you can hear what you are saying.....
