1989 Passenger side electric window issue

[Sanchez_005150]

Hi all, I recently painted my car and have started putting it back together and have had an issue with the power windows come up. After putting the entire door panel together, the passenger switches are non responsive. Ive checked and confirmed there is in fact power getting to the window passenger controls but there is not movement from the window or the window locks. The drivers side works fine in controlling the window, but also cannot roll down the passenger side or lock/unlock either door. Both window motors were replaced about a year ago and the fuses that are associated with the windows to no avail.

I was thinking it could be the switches on the passenger side but the fact that the drivers side wont work for the passenger itself makes me believe that it's not the issue. The door locks not working at either side also leaves me to believe that it's not the switches.

ANY information would be greatly appreciated. Ive looked at a bunch of other threads and have not found anybody that has had this scenario. Thanks!

For Clarification:

Drivers Side Control:
Driver Side Window-OK
Passenger side window- NOT WORKING
Lock/Unlock Switch- NOT WORKING

Passenger Side Control:
Passenger side window- NOT WORKING
Lock/Unlock Switch- NOT WORKING

THANKS!

Electrical - Passenger window does not work

Hey guys. I’ve got a 1992 LX. A while ago, I got into an accident and replaced my interior driver door with an OEM 1989 door. Since then, my passenger window hasn’t worked. Replaced the motors today, and it still doesn’t work. When I hit the up button on the passenger door, I can hear it engage...

Alot of good information in this thread. Would door actuators or the door motor prevent the passenger door from rolling its window up or down? Thats whats really got me confused since it was working fine a few months ago.

Your window motor has taken a dump you have a wiring issue.

Get your trusty volt meter out, remove the door card, and check for power at the window motor.

Will check on that. Would the motor effect the door locks?

Nope... The door lock actuator, affects the door locks.

Answered this over on the other forum

Check connector C315 to make sure it's plugged in. It's in the LH kick panel.

The way the windows/door locks are wired, the signals go from side to side to make things happen. Only takes one connector to be unplugged to mess things up. Given what you stated works, my guess is it's C315. It's the one connection I feel would kill both door locks and pass window control, but allow you to have power on the pink wire at the pass side window switches

I know this is not electrically related, but I had to grease the window track, gears and make sure that everything slid well or the window would not go up.
