Craig,

Thanks for the excellent link.

Apparently the module I originally mentioned will not work with most Mercedes.

I was told that on most domestic cars when the power window switch is hit that the current to the window motor is supplied. A permanent ground is in place in this type of circuit.

With the Mercedes and some other Euro cars the switch completes the ground circuit for the motor.
