2004 Yukon SLT - Weird electrical issue

[JochenWoern]

Good evening All,

Yesterday all was good, this morning all was bad. I know I used the lumbar support yesterday while driving home from work.

Well needless to say, when I got in the truck bright and early this morning, seat heaters are NOT working. Turns out that passenger seat heater does not work either. Then I tried to move the seats, does no longer work, same with the passenger seat????? Right side (passenger side) windows do longer operate from the drivers panel nor from the door individually, but the drivers side windows work.

Checked the fuses which are good.

What is the issue here????? I am puzzled.

Thanks for your help in advance.

Have you checked ALL the fuses? Also, try unplugging the battery on the truck for a bit of time and see if that helps solve your problem!

Thanks for the reply. No, I have not checked ALL the fuses but the ones pertaining to the power seats, windows and seat heater I have checked and those seem to be good.

I will disconnect the battery and see what happens and will advise accordingly.

Thanks again.

Checked ALL fuses, no signs of a bad one.

Had the battery positive disconnected for about 20 Minutes. Reconnected the battery, unfortunately NO change.

Dealer suggests it could be the driver door master window switch assembly.

THOUGHTS???

I guess it could be the window switch, I know when I was changing out the lights in my drivers window switch I didn't solder all the pins back in correctly and boy did it screw up a bunch of stuff until I finally figured it out and fixed it! There are alot of circuits that are affected by that switch, so maybe they have an idea!
Do you know of anyone with a tahoe or yukon that you could swap window switches with to test their theory? Maybe take yours out and make sure that the harness plugs going to the switch have a good solid connection, unplug each one and plug them back in and see if that's the problem!

Unfortunately I do not have anyone around me where I could just swap the switch with. But I guess it would be worth checking if all is connected properly, as I am still puzzled as to why things went sour from one day to the next?

Do I need to remove the door panel to get to the switch, or will the switch just pop out from the top of the arm rest without taking the panel off?

Many thanks.

My switch just pops out but mine is an '02, I can't remember but I do think someone mentioned in another thread that the panel has to come off on the newer ones!
To be safe, pop the panel off and check your connections, hoping that is indeed your problem!

So, did you figure it out?
