I decided to investigate.First off, the switches. No problems there, contacts were clean and everything functional. Circuit breakers? All okay.Swapped the switches around and still nothing was happening. Removed the door panels, checked the power to the switch and the motor and there's power getting to both.Then i noticed a little "thuk" sound from the motor everytime the power window switch was pressed, either up or down and for both doors. Ran the test again later at night and noticed that the cabin lights go dim whenever the switch was pressed.So it sounds like the motors are trying to work, but are stuck.Sprayed WD40 around the place, no improvement. Had a look at the mechanism, looks complicated and partially hidden.So does anyone know of a way on how to take these suckers apart and service them? Or at least a place that is competent enough to do it? Don't want to pay $$$ for new motors laa...</p></blockquote><p></p>
