I have a 2001 Continental and the Door Ajar Light is constantly on as well as electronic Drivers Seat adjustment as well as the electronic mirror adjustment are not working. I had the drivers side door control module replaced and that fixed the door ajar light from comming on. Is there a seperate module for the seat and the mirror adjustments? Is it an easy do it yourself job? Also one of my spark plugs isnt firing correctly (32V V8) and after replacement it continues to fail. Any help is much appreciated.
