My 91 camry has power windows, but the driver side controls wont roll down any of them [even the driver window] the window and door lock buttons work but thats it. I have switched it out with one from the wrecking yard but the same thing happened.

Do they work from actual door switch? My guess is master control on drivers door is going bad.

Sounds like the master switch is not plugged in properly, this is the switch in the driver's door.

The power locks have absolutely nothing to do with the power windows - totally different circuits.

The FIRST thing to check is to make sure that the window lockout button on the driver's door control switch is not turned on. This will keep all of the windows from operating except the driver's window.

Other than that, there are several things that can cause a power window to not roll down. It can be a power window lift motor, a window regulator, the window switches, or any of the wiring in between. Also, you did not mention which window is not working. BOTH of the FRONT windows are equipped with Door Control Modules (DCM) which, in turn, are controlled by the Body Control Module (BCM). If it is the front window you are talking about, it will be necessary to scan your BCM for fault codes to determine the source of the problem. If it is one of the rear windows, this can be checked by regular electrical testing and a scanner should not be necessary.

either the switch in drivers door died or plug came off

The regulator is burnt out and you need a new one. I would just replace it.

thats cause that what the lock is for so it wont go down

No won't be fuse. My guess is there is something faulty with the main controller. You could probably verify this by trying the switch on right rear passenger door. If it works there then the problem is at the main controller in the driver door. Could be a loose wire or the switch itself is broken.

have you got the child lock button pushed down it would have a picture of a window with an "X" on it also have you checked all the fuses in your fuse box

most of the time it is wires in the drivers door that break in the loom

I had the same problem with now power to windows, mirrors and seat. The common soulution is the orange and or black wire in the boot have broken between the door and post.
