so this is getting really frustrating. the passenger side window/lock only works once and a while. i know it won't work when the illuminated buttons are out. the lights will come on and go out again. very random. i thought it would be the window/lock switch, so i bought one and plugged it into the harness, but still the same situation. being winter i dont want to roll my windows down and not be able to put them back up during a storm.

 

since the lights, lock and window all don't work at the same time, that sounds like a power supply issue to the switch assembly in the door....either a bad wire connection or a faulty BCM.

 

.... Next time it does it check those connections at the harness with a circ tester. Specifically the power and ground.

 

a little update. situation is still the same, but now the window does not go back up at times when you open the door. driver and passenger side. GRRRRR......

 

i have the same problem. i dont think its a power issue because if i plug in my drive side switch i get power its just that switch. i try to figure out what is the root but i dont think its the bcm? is it? that seems a little extreme to me.
