Power windows

My power windows weren't working when I bought my car. I figured it was just the plastic pieces inside the motors, but apparently not, neither side will move when I press the switch. I checked the circuit breaker in the fuse box, and it was good. I swapped a known working window motor into the drivers side (havent dissected the pass. side yet but it makes a faint noise) and no movement or noise at all. I am not too sure how to check and see if the switches are getting power or if the fuse in the fusebox is getting power, I guess thats what I should check next?

I would check for power in the door when the switch is pressed, then move to the switch it's self if you can't find any power in the door, then move your way to the fuse panel if you can't find power at the switch.

I just double-checked, and it dosen't seem to be getting power. With the key turned on and pressing the window switch - nothing. Gonna check the switches now (which I know have been replaced because I found another switch panel in the trunk) just not sure which pins to check, so I will check them all I guess.

I have 11.20 volts at one pin on the switch, nothing on the rest.

I have my 88 EVTM here it says you should have power at  R/LB wire at the switch.

I'm assuming you are working on your Mark VII

Yes you are correct, and that is the wire that is getting the 11.20 volts.

it says to make sure your black wire has a good ground

 the actual ground is on the rocker panel driver side under the carpet

So I would have to follow the black wire from the switch to its grounding point?

Yes , but an easier way to check would be to take a jumper wire and ground the black wire from the switch to some spot under the console, then try your switch to see what happens


I'll wait here :D

Ok, grounded out both black wires on the drivers side switch, nothing. When I press and hold the switch for the passengers side with the key 'ON" all the warning lights that come on will dim, this does not happen with the drivers side when I hold it down.
