The driver's side window on my wife's 2001 C240 has stopped working. I can hear the relay working but no response from the window. All other windows, the seat and mirrors all work. I recently had issues with the seat control module draining the battery and had cut the always hot wire to isolate the problem. The window issue began after I reconnected the hot wire on the seat controller.

The window fuses are ok and I'm not sure where to go next.

TIA
