I will look into doing this. Any idea if this type of tool is good at getting the door trim off? http://cgi.ebay.co.uk/CAR-DOOR-BODY-REPAIR...6QQcmdZViewItem Just to confirm, operation from the door switch is perfect. Dash switch and C/L is incorrect. My ideal solution would be there is a way to change the wiring to correct the operation. Rather than have to obtain another unit, remove the current unit, courier it back to the breakers and get a refund, etc. This is the second replacement part so far, first one was completely duff. Any idea where I could obtain a wiring diagram from?
