How common do the master window switches break? - SOLVED

[915_Tahoe]

May need to be programmed or reprogrammed the master switch. Some vehicle need that switch to be programmed to the vehicle.

Just Replaced the switches and unfortunately still having the same Problem. I know All of the switches are getting power since the backlights are on at night. Hopefully I can figure something out so I don't have to go to the dealership and get honey dicked.

Did you ever figure out your problem? I now have the same thing. After doing some online research I'm leaning towards getting a new door harness.

Where the wiring/harness goes thru the door jam at the hinge area, is where to open up and inspect for damaged wiring. Also, did either of you pay attention to what @915_Tahoe said about reprogramming?

I got in my vehicle a few days ago to find that almost all of the switches on the driver door had stopped working. The only switch that works is the drivers side power window switch and the Lock/Unlock button, all the other window switches including the side view mirror adjustment switch will not work.

Has anyone seen this before? I purchased some GM replacement switches so hopefully that works and it's not something deeper like the wiring harness.

Seems to be a common problem. Mine just quit also. Looks like they're abt $125 to replace.

I just ordered a new wiring harness from GMPartsgiant. They give you the ability to verify that the part will work with your vehicle by VIN#. On top of they had a great price, harness was $120 including tax and shipping. If you have a 2015 the part number is 84305359.

I never did. I kept trying to get an appointment with my local dealership but never could work out a good time. I need to call them Monday and see if they can get me in now that I'm not so busy. Let me know how the harness works out.

Picked up Covid on a business trip so it will be awhile. Plus I started a major brake project on my 03 Suburban. I'm replacing everything from the booster on down.

I forgot to update this thread whenever I got the problem fixed. It ended up being a blown fuse, specifically #18 "Mirror Window Module" fuse in the drivers side fuse panel.

Hopefully that might help someone with troubleshooting this issue in the future.
