I have just picked up a T4 with electric windows & mirrors. The passenger side electric window winds up OK, but only winds down about half way. The driver's side works fine. I have done some reading on the forum already which seem to say that it needs resetting and to do this all I need to do is hold the button in the up position for 30 seconds after winding the window up. I have tried this several times using the switch on the passenger side and the passenger switch on the driver's side, but it hasn't worked. Has anyone got any ideas? Thanks.
