Power Window problem

[ALLNAMESTAKEN91]

Ok, so I have a problem with my windows, For some strange reason all my windows will ONLY operate with the driver side panel, except for the Rear LH side won't operate at all. The Rear LH side window will roll up and down if I supply 12 v. from the battery, so I know the motor isn't bad. I have tested all of the connections up to the fuse block at the driverside kick panel. all the fuses are good. Anyone have any suggestions?

you probally have a switch problem. you can take the switches apart and clean the contact or just replace the switches

On my 89, the passenger side went out and I bought a new motor for it. However, when I finally went to replace the motor, it was the wrong one! Anyway, I was bummed, but while messing with trying to get the new motor in, the window started working a bit. I read somewhere that if you spray a bunch of WD 40 on the switch, that might be the problem so that's what I did.
It worked. At first the switch worked sporadically, so I sprayed some more on it and its been trouble free for over a year now.

Finally after hours of learning electrical, tearing shit apart and tracing wires and scratching my head to the wiring diagram, I finally discovered that all of the windows are sent to a relay in the driverside main control switch panel. Turns out the inside is all corroded and the power isn't getting routed to ground like it should be. So looks like im out a switch!

This is on a 4 door runner, right? You should be able to pick that switch up for a decent price. I think it was used on other 4 door Toyotas as well.
