Power windows with no bcm
Hello i recently joined the forum to ask this question. Ive search all over the internet and can not get/find a answer. I have a 2010 that has been gutted of all wiring. Its a drag car only and has a bbc and pg in it. All the original glass is in the car and i want to get the drivers side window to work. I have the factory window regulator, door panel and switch. But i cant figure out how to wire this thing without the signal wire from the bcm. I fried the window switch already jumping wires around to try and trick the system.(new one on the the way) and i dont want to go about this on a trial and error method(could get expensive replacing parts) has anyone powered their windows without the module? Thanks for any help and sorry for the drag on question

It needs a BCM to work, or you have to mimic it.

Here is how it works, the switch has no way of powering the window motor, its a resister with two value settings, one for up and one for down, it ties in to the BCM on a lanbus, so when you push down that value is transmitted to the BCM, then the BCM tells a relay to put power on the wire that runs to the motor, if you push up the same happens but polarity is switched.

Okay thankyou. So it seems trying to mimic is damn near impossible. Can i bypass it. Take the motor apart and hard wire it so to say. Eliminated the circuitry in the motor. Get a different switch or modify it to send power to the motor f ok r up and down function

I'm not sure it's the solution you're looking for, but I made mine work by bypassing the window module in the motor, I hooked it up "old school" and set up a remote and relay system so I can bump them down to open and close the door.
