Ok ... yes, tried to swap them .. no change. I have meassured all wires through the A pillars and no shorts found.

One thing I cant figure out is .. when boot motor is hooked up there is Batt voltage on the red (red/yellow) wire as expected on all motors, but also I have around 11,7v on one more wire (the yellow/green I think it was) ... this voltage dissapears (not the batt woltage on the red wire) when boot motor is disconnected.. but either way, with or without the boot motor hoked up, the master motors run cracy when I put them in the unluck position ? But boot motor woks aswell as the left rear motor.

I'll hopefully get a little time tomorrow to have another look at it ... as I supect that there is a connector problem in the both front doors as I could actually stop the motors running by moving the connector ...?
