Time to crack out the multimeter to check the door looms, and take a look to see if the connectors in the A pillars don't have any green corrosion on the pins.



It is a windowbus fault, but where is the question

Well, I’ve been busy at work so haven’t had much time to do car related stuff, especially on the project gold car.

Haven’t taken the door off to check the connectors in the A pillars as recommended.🤭
But I did take the multimeter out today, to check for a residual battery drain.
Turns out I’ve a drain of 170mA, when the car has gone into sleep mode.

Pulling fuse 32 (remote door locking / interior lights) in the passenger footwell drops the drain to 40mA.
- interior lights still function, but not as a courtesy light when door is opened.
- drivers door module doesn’t operate any windows at all, but all windows, except drivers door, operate by their own module.

Pulling fuse 35 (front windows) drops the drain to 70mA.

Must do as suggested at some point, as it looks like battery drain and non functional window operation are linked.🙄
