So not a relay fault then. Check for 12V feed to the motor. if nothing there introduce one to confirm the motor int goosed. then check wiring for continuity between switch and motor.
Good news, I have 12 Volts at the door when pressing the switch, buzzed 12v on the motor and not getting anything out of it so hopefully it's just a motor change.
Opened the door up though and I have this cable which I am getting a constant 12V from, cable colors are orange @ pink. Any ideas anyone?
