Mazda mx5 window fix 

Holy crap. Buddy, you are my hero. My son's driver's window (USA, left side) only worked occasionally. It had this exact failure on the same pin. Obviously a design flaw. You saved my untold hours of debug time. Thank you.

cheers, saved me a fortune, same problem, same pin, no solder on pin at all, resoldered it, window working again, result 😂

Thanks for the video, used it to help my son diagnose the issue on his MX-5 NC. Hopefully as a useful tip for others, you don't actually have to lift the centre consol fully out after struggling to unclip the connector. You can just reach under and press the metal corner tabs on the switch module allowing it to pop out with the cable still attached. You can then screw the consol back into position until you have the switch unit fixed when you simply clip it back in. If you have a dry joint then just flexing the connector whilst popping the switch unit out typically gets the connection back up and running as a temporary fix anyway.

Woohooo!! Thank you, same failure on my US drivers (left) side window. Window was intermittently failing randomly until it stopped working entirely. Same pin.. we probed the resistance between the header pin and PCB trace, and found a 0.5 ohm resistance.. it presumably increases as the connection wears, until the resistance drop across the connection is too high to drive the motor. Anyway, thank you again, I love Australians!!

Gavin, You and your friends made my holiday!! I was traveling in France when my window of my MX-5 NC didn’t close anymore and my roof could’t open anymore! Your video helpt me out! Thank you so much!! Frank Smits The Netherlands

Hi, I have a 2008 GT PHRT, thanks for your video, every year the problems increased, I am doing the repair and hope when I put the battery in the car this spring that everything will be fine. Thanks again, it’s much appreciated.

Just wanted to say a massive thank you guys! Recently purchased my first PRHT knowing full well the roof didn't work, did this and now its fixed! Thanks a million from the UK!

Thanks. This helped me get my 2012 Miata switch working again. Live in FLorida and it rains a lot!

Thank you, thank you , thank you! This resolved my issue (twice). The first time, a year or two ago, I did a bad job of soldering, this time I did a better job. Having a US 2008 model, it affects the driver side window. A replacement switch is currently about $200 US dollars. Also, the entire boot over the parking break comes off quite easily, on my car, so it isn't as tough getting the console back into place.

This video saved me over 500 euros! Thank you very much for the detailed explanation!

Shoots! I have this issue for almost one year. Opened it and only looked at the golden contacts trying to find oxydation... Without success. Finaly I ordered the part on Mx5 parts for 130 EUR... Didn't received it yet. Too bad I didn't saw your video before. Hats off and thank for sharing!

Gavin, thanks so much for this video. I have a 2008 NC. Followed your video carefully and SUCCESS!!!!!

Thanks Mate! My daughters passenger window switch and PHRT roof wouldn’t work so doused the window switch with WD-40 as a temporary measure and it worked perfectly. I will get around to soldering eventually.

I just want to thank you both for wonderful video. I had two friends helping me over the past month or so and After I could not do a perfect job with a soldering iron that would not heat up to the required temp, My friend brought his better soldering set up yesterday and got a perfect bead build up on the gpu contact. I put it back together and turned on the ignition and we both just dropped our jaws with shock and delight!! Woopee! The cost of the switch part for me with Miata Club discount was going to be $250, not as bad as yours but still on a retirement income, I pursue all self repairs I can.

Thanks mate fixed my passenger window this morning one tip I removed the handbrake rubber just clicks off made the console off and on much easier! Thankyou!

Thanks so much for your video. Saved me a ton of money. My drivers window would intermittently not work at all. Found a bad solder joint on the board, different one than yours. Works great now. By the way if you have to take your center console apart again, your emergency brake boot just pops off.

Can't tell you how grateful I am for this, another UK owner. Very clear instructions, the fault was identical to yours right down to connection on the PCB. Saved me hours.

Thank you so much for the video! Same issue in my 2008. This video saved me $250 USD and, more improtantly, hours of trying to diagnose this in the North Carolina summer heat. I was able to get the interior panel off with the wiring harness connected to the window switchs after disconnecting the parking bake switch and the harness tiedown on one of the shifter studs. A magnification light helped with the soldering and watchmaking tweezers helped a lot to get the PCB screws back in place.

What a fantastic video. My dad and I just went through this same process to fix his NC Miata. We wouldn't have been able to do it without this walkthrough on the issue, disassembly, and soldering.

Your fix worked on my car, Sirs. May you each live to be one thousand years old. Thank you. My mom had to loan me a small screwdriver to get the wire disconnected. Mr. Michael Griffin

Thank you. My 2009 Mazda Miata MX5 GT has a power window broken. I will look at this. Thank you for such detailed information. Thank you for saying 99% tin and 0.7% copper. Who knew? My amateur radio call sign is KF5LJN. My friend Rob May W5WS told me the Weller WES51 is a good soldering iron. FYI I bought a Fluke 17B+ Digital Multimeter. Rob said that one has a better internal circuit protection. I like it. Anyway thanks for the help. My mom might help me open the console and get the correct solder. My car sold new in Austin, TX, had two owners in Arkansas, then an airplane pilot bought it in Texas at auction and now me. It has problems, but Mazda made a strong machine. My VIN begins with J indicating made in Japan. - Mr. Michael Griffin

I wanted to add my thanks as well. Dude! Thanks! My '07 MX-5 with PRHT and Automatic trans had the same issue. No mechanic near me would touch it. Followed your instructions on getting the console and the switch out, with some minor differences. My switch had two connectors and there was a wire connector to light the Automatic Trans panel in the console. But when I got the window switch out, it had the same badly soldered pin. For the price of a little soldering iron, I got it all back together and working perfectly! Thank you so much.! From the other side of the world in Atlanta Georgia, USA. Blessings friend!

Thanks for the vid. After loosening the console I managed to pop the switch by wrestling the 4 clips while prising the unit from above. THEN disconnect the 2 wiring clips on my 2009 NC PRHT auto. The part number for this one, black, reads N174 66 350.

I had the same problem, followed your video, took 30 mins and it worked. Thank you so much, saved me a lot of money.

Thanks so much mates!! You saved me a €300 switch replacement, my driver's side window and power roof are finally working again! I would buy you a drink if I could

Your a hero we've had a parade in your name here in America thank you 👍

You are a bloody life saver mate! You just saved me a massive bill at the Auto Electrician and my wife now thinks I am a fecking genius. THANK YOU SOOO MUCH!

I just want to say thank you a million times over. I had the same thing happen to me off and on for awhile. Today the window finally wouldn't come back up. Called the dealer to order a new switch. You guys just saved me $150 us dollars. Did exactly the same thing you did in your video and it worked like a charm. Thanks again for this video.

Absolute legends!! Thank you both so much for sharing your experience. Your video gave me the confidence and information I needed to give it a go and it worked a charm. Huge thanks!!

Guys, thanks so much for this. Some forum walkthroughs about but this is class. EXACT same issue with my MX-5 2.0lNiseko hardtop. Passenger window went out of the blue, couldn't take down hard top. Window half open and it's cold and rainy here on the mud island. Fixed up in a couple hours today. There must be a factory defect with that unit, because it's quite common that DPU contact failing over time and none of the others.

Legend!! My window (and PRHT) stopped Sunday morning while I was out driving. I spent the trip home wondering how I'd get it to the auto electrician during the week. Your video was the first one I watched from my Google search results. Had the window fixed Sunday afternoon so I went for another drive. Because I already had a soldering iron and solder, it cost about 5 cents.

Saved me quite a bit of money and frustration. Thank you 🙏

Thanks for sharing. Had the same issue (driver side - US model) followed the video and resoldered the part. Be careful when removing the small plastic cover from the motherboard, the two plastic connectors are really filmsy and can break easily.

Excellent video! My son, Gavin and I were able to repair the exact same issue in our 2008 PRHT. The only difference was the configuration of the center console. Thanks again!

Thank you!!! Watching you gave me enough guidance to pull my 2003 switch out of the console and simply clean it up so it would start working again. I would never have pulled it apart down to the circuit board without seeing you do it, and that's where the problem was, so thank you. I felt most victorious when the window worked again!

Gavin, just want to tell you guys how much I appreciate your educational video!! I am dealing with this right now and your video helped me a lot. I elected to replace the switch because it is not as expensive here in the US. I dont sauder. I use the trim tools on all my Miata interior kit. FYI, I also removed the boot for,the brake handle as needed like for the gear shirt. And I have a different after market center piece replacing the cup holders. So 4 screws not 5. My car is also Copper Red GT for 2008 and is LH drive of course. So many thanks!

Excellent and informative video. Saved me $500 for a new window and switch the mechanic wanted me to get. This was for my 2011 Miata nc2 sport automatic and everything was the same except for I didn’t have to take a piece of plastic off in front of the shifter.

This fix worked for me as well in the UK. I bought a trim removal kit but struggled a bit in getting the 60/40 solder (with flux core) but eventually got to do a decent solder of the joint. Fingers crossed that joint holds but if it fails again I know what to do. Many thanks for your posting saved me a small fortune

My 2008 MX5 just started having the same problem. I disassembled the switch and cleaned the contacts but I missed the cracked solder joint. Thanks so much for your video of the quick and inexpensive fix!

OMG! You guys rock! Totally saved me from losing my mind on the windows of my NC. Thanks so much for the video fellas.

Thanks for the video. I would have never tackled the problem without your lead. It turns out that the solder on my circuit board was fine, but the "down" contact on my passenger side (right side in the US) rocker switch was corroded. A few scrapes with a small screwdriver cleaned it off and saved me $120 US!

Thanks for the tip on releasing the switch wire, it absolutely saved me.

Much appreciation for the video. I had the same problem with my 06 soft top (left/passenger window in RHD) The pins were in a different arrangement but had the same faulty DPU pin. Thanks again for creating this video.!!!!

Great video...saved me a load of time and expense, thank you! Same problem here - passenger window stuck - although we bought a replacement switch, genuine Mazda part, black, which only cost £89 here in the UK! Quite how Mazda Australia can justify those prices is beyond reason.

Thank you: Have been trying to fix this problem for a while now, haven't been able to source a second hand one in NZ, was about to order a new one from Japan [$790] so happy to have found your video. Managed to get the window switch out without taking the console apart and no damage done, but have made a tool to make it easier if I need to remove it again. Thank you again.

Legend. Fixed my 2008 PRHT within half an hour.

Thanks for this. Had the same problem. Following your video I fixed it myself. Thank you SO much!

Great vid and instructions, thanks for your time and effort involved 👍

Thanks boys fixed mine in 30 mins with this video

Great clip! I had the same problem on the same window (left side) but I'm in US so mine will be the driver side. I opened it up and the exact pin had the problem.

Well done lads great video, will remember this is if mine ever stops working.

A big thankyou for making this video I live in New Zealand and own exactly the same car I have been having intermittent problems for a while until the passenger side window stopped working along with the power roof, thinking this was going to cost me a lot of money I found your video and followed it and checked the circuit board and found it had a dry joint in the same place, so now I have windows that work and a power roof that goes down, best Christmas present I could have, thanks again and all the best, and Merry Christmas 😁👍

Just used this to fix my MX5 many thanks for putting it up!

Valuable information. Thank you

Thank you for this video/walkthrough. Helped me immensely and saved me $$$.

Would have been easier to push the switch in after the console was already down. This would make it easier to plug in the switch. Pro tip (I was a professional electronics specialist): There is a product called Solder wick. It absorbs melted solder. 😊

Just fixed my 08 Miata, driver's side (left) switch won't work. Exact the same problem with the pcb. Many thanks!

Besides soldiering that DMU connection, either trim the pin or relieve the plastic where it hits. That is why that soldier cracks around that pin.

THANK YOU SO MUCH< EXCELLENT VIDEO!!

Thanks. Great video, Worked for my 2008.

Great video guys. Thanks

I have a 2006 Mazda Miata MX-5. The tab which controls my passenger window has come loose and, obviously, the window is not functioning. I just need to figure out how to reattach the part or replace the entire unit. Any help would be greatly appreciated.

I made it to 5:21 before deciding "I'm taking it to a mechanic"

Thank You! Very helpful!

you are a lifesaver

Exactly what my problem was

My drivers side door randomly stopped working last night, the switch still clicks,but no window movement. Do you think it’s the same issue you had???

It works Thanks!

thanks for lovely video. cheers :)

Yeah. Mom wants to help.

I just happened to come across your video while searching for how to remove my door handle from my 2008 MX-5 GT RTH. I decided to watch it because in 2019 I had the same problem with my driver's side window not working as well as my retractable roof not working either. So I watched your video to see how you resolved the problem. Back in 2019 I could not easily find a solution to fix my car, so I had to resort to Trial and error. At 1st I thought it was the window regulator and bought a replacement, but it wasn't. Then I tried to replace the center consul switch, but the replacement I got from the salvage yard was from a 2006 and I ended up blowing a fuse. I eventually found this discussion in a forum ( forum.miata.net/vb/showthread.php?t=606768 ) and decided to take my switch apart. Guess what... my solder was broken on the same pin as yours and the one in the forum. I soldered it over the old solder like you did and that fixed my window and roof problem too. It's been working for two years now. I wish I had come across your video back then, but you had not published yet. I just wanted to share my similar story. Your video was good and I'm sure it will help other's with similar problems. Thanks for this video, now I need to keep searching to find out how to remove and repair my door handle. I have keyless entry system and the rubber button in the door handle is worn, so I ordered a replacement button on eBay.
