Hi all, I'm having some issues with my power window. When I bought the car they weren't connected. First of all I tested the motors with 12V directly and they work perfect, however they are Bosch FRE 12V and not the original ones. After reading a lot from Wilcox and this forum, I followed all the instructions to check the electrical scheme and test the circuit breaker, relay, and switches with a 12v light screw and everything seems to work, or at least turn the light. Nonetheless I have power from the switches to the motor, they are no able to function from the circuit power. Any idea about what this can be? good motor, apparently good electrical circuit but not working together? I want to try to fix myself the problem, because this is where I found the fun!

Thank you!
What year is the car... that'd be a huge help in me knowing a way to steer you.
Of course, it's 76. Thank you for your videos and especially for your tech section in your web! it has been a great help for me.
I was thinking in change all the cables for new ones because they look really old and maybe some of the currents is being lost or there is too much resistance.

If you follow the instructions below.... to a T... you'll figure your issue out....
It sounds like you may have problems with a wire. You can read 12 volts but may not be able to carry current. If a wire is almost broken (lets say two strands out of 12 )you will read voltage but when there is a draw for current it will not pass. Check all the wires for cracking or partial break. You can use an ammeter to check for current along path but will have to be a good one as may be up to 30 amps. good luck
Yes! and It works! I grounded the motor direct from the battery and connected one of the wires from the switch and the motor workes! So the issue seems to be ground to the motor. According to the wiring diagram, I only see ground in the circuit in the relay and I think that ground it's working because the relay seems to work fine. (I assume) Following your instructions I can´t test terminal F removing the connector because I have only one connector for E and F. Do you think it goes something to be with the old wires? both conducted the 22 V to the motor. My multimeter reading was: battery 18V, Relay 21V, Switches 22V, wire at motor 22V Is it normal? more than the car battery?
