Hi,
I need some help. I have the Passenger front Lock and Window not working almost at the same time. Also the rear passenger lock not working. I have changed the window regulator/motor in both doors. I have changed the ECU module in both as well. Still not working. I can open the rear passenger window from the rear, but cannot do same from the driver control module. I am just wondering if all these are linked together? Or is it that they ECU or motor function independently, if maybe one of the used parts I bought are also faulty, like the ECU or window regulator, and that I also need to change the door lock for both. Any advise please?
