I have a 2007 chevy tahoe LTZ
My passeger door seems to have no power. The power windows, door lock, heated seat, power mirror doesnt work from passenger side switches. Cant make anything work from drivers side switches either. I checked all the fuses on drivers side panel and under the hood. I replaced the passenger side switch module but it makes no difference. Please help iman electrician and have no clue what to try next.

 

Christopherj, WOW, you have a lot of stuff going on her, or rather not going on here. Do you have any schematics for your Tahoe? Also, did everything just stop working at at once or was this a gradual thing and one this stop and a little time later another? Did anything happen to the Tahoe recently like an accident or a repair of some type? Do the back windows operate fine since you said the fronts did not work? Also, (sorry to hammer you with questions back) but I know my 2014 Impala throws trouble codes if I have a short to ground or +12V, I don't know if a 2007 does, but did you try scanning for any relevant DTC codes?

 

check for broken wires in a-pillar of the passenger door...pull back the rubber grommet....the wires flex each time the door is opened...10 years of flexing
