Electrical Help

I know this isnt LS related but i been stuck on this for a while now.
Im trying to wire power windows in an old truck, 56 chevy. I dont know where the power window kit thats installed came from. All i know is that it uses standard GM switches...

Now i have wired the double switch to control both windows, the problem that i run into is wiring the passenger side switch. If I wire it, it shorts against the driver side switch... I tried wiring in a pair of Relays to the drivers side switch to make it independent but then it wont work because it cuts off the ground making an open circuit. PLEASE HELP ME!!!

This is how the switches work. The drivers side is just a pair of switches that work in exactly the same way. This is the back of the switches.. The window motor just has 2 wires coming out of it, polarities need to be completely reversed in order to make it go up and down. The power door lock was easy, it had 3 wires coming out of it, ground and power to 1 wire make the actuator lock and power to the other wire makes the actuator unlock.

There's no need for relays here. It looks like standard window wiring to me.
Okay, lets label the switch terminals and the motor wires to start with.
for the switch
1 3
2 4
* 5

For the window motor, call one wire W- and the other W+. When done, you may have to reverse these to get the window to go in the right direction.

Okay, on the passenger door, connect W+ to 2 and w- to 4. Connect +12V to 3. Now, run a wire from 1 of the passenger switch to 2 of the remote switch on the driver's door. Run another wire from 5 of the passenger switch to 4 of the remote switch on the driver's door.

The remaining connections are to connect ground to 1 and 5 of the remote switch on the driver's door. Lastly, connect +12V to 3 of the remote switch on the driver's door.

Now, either switch will control the one window. If you press both switches in opposite directions at the same time, there will be no short.

This is the way cars were wired before electronics took over. If you wanted a window lock switch, it would connect between +12V and 3 of the passenger switch.

Enjoy...

thats exactly what i was thinking but.... that leaves both window motor wires grounded and when you try and power from a different switch it shorts.

Joe - your posts are typically spot on. On this one, I would always recommend the switch driving a relay, and the relay driving the motor - isolating motor current from switch. it will work either way, however usually the switch drives the circuit, ther circuit drives the motor.

where in the circuit are you placing the other switch?

THANK YOU SOOOO MUCH!!! Answered everything in 1 post! Now time to get busy.

Quick, those switches were made to handle window motor current. This is exactly the way my 91 Grand Marquis was wired. There were no relays.
Oh, and thanks for the compliment.

An even easier solution.
