Could someone provide me with a wiring diagram ofthe drivers woor. I have no power to the left side window switch. Thanks in advance.
You have done a continuity test or are assuming there’s no power to the switch?
Pry the switch out of the arm rest and test it. (You don’t say what year your van is)
Is the switch dual control? Switch for drivers window and passenger window?
If there’s no power to the switch from the fuse panel, there may be a damaged/broken wire at the door/door post (inside the wire cover) from years of opening and closing.
