module for window roll up and down?

Let me ask this one more time:

OK, do you guys know were exactly on the Lexus GX 470 or LX 470 is the window auto up/down factory module is located?

Could it be possible that the  Lexus GX 470 window auto up/down factory module is build inside the switches that goes on the drivers door.

My Toyota Land Cruiser Prado, only have Auto Down on the drivers door. It does not have Auto Up. 

I know the Lexus GX 470 has Auto UP/Down on the four doors on the driver side window switches and thats why I am asking if the Auto Window mudule is built inside this switches.  This way I can try to get this driver switches and install it on my car.

Most newer cars (esp. Japanese) use a very complicated obstacle detection system that is way more involved then just a switch or motor.  They typically have an encoder built in to the motor that sends pulses back to the power window module.  If the puleses drop below a certain frequencey while not at the beginning or end of travel the windows will stop, and in most cases roll back down.

Other cars use current draw for anti pinch.  If your car does, then the swiches might be swappable.

Also, you should never drive windows with relays alone, as you won't have any anti pinch protection and you'll slowly wear your motors out.
