I have been working on this project for a bit, so thought i better write it down somewhere   The AUTO switch is part of the Lin bus system (Multiplexed) and controls the motor over a single wire from the driver's door switch, the switch on the passenger door controls the motor, all the control system is in the motor The problem is even if you put a LHD motor in the passenger door you still need to get it to talk to a master switch - that leads to having to change the master switch
