Odd power window problem

[aidandj]

So I have a 2000 z71 OBS and I just started having a problem with my power windows. They all work from the drivers seat fine but none of the other switches work. This started when I locked the windows once. Then when I went to unlock then they wouldn't go down. Now no matter what position the lock switch is in none of the windows roll down unless I do it from the drivers seat.

Update:
I just went and tested them again and something even weirder happened. I unlocked the windows and tried the back window...success! it went down. I then walked around and tried the passenger side...no luck. For a second I thought the passenger side wiring must be shot. But then I went and tested the back drivers side window and it didn't work either. I'm stumped.

your window lock could be have intermittent malfunctioning form internal electrical arcing.

Sunlitcomet, how would I go about diagnosing/fixing this?

First remove the switch panel off your master door and tell me what color your wires are on the lock switch. Dark blue and yellow?

Sunlitcomet: Sorry about the late reply, I was at college orientation.

Yes there are 4 wires: Yellow, Blue, Black, and brown

if you short the Yellow and dark blue together you are bypassing the switch and all the other windows switches should operate normally indicating a problem with the windowlock switch if you still have window issues the problems is elswhere.

Sunlitcomet: So i should just pull out those wires and touch them together?

Something like that just make sure you have a good firm contact without damaging the terminals. or use a jumper wire with firm contact in the plug. try you window lock out a few times and try bypassing it . Go back and forth to be sure the switch is the faulty part.
