Automatic Windows on 2002 Pontiac Montana

Need a new wiper motor.

drivers side between door and dash or under dash drivers side,

Junk the stupid van and get something else

Would you describe it as an extended crank? It cranks over a lot longer before it starts and then maybe runs a little rough for a bit and then clears up?

If so the first thing I would check is the fuel pressure regulator. It is on the drivers side front of the engine right next the the throttle cables that attach to the throttle body. Remove the vacuum hose from the top of it and start the vehicle. If gas comes out it will need to be replace.

before replacing get a can of silicon spray and spray on the runners this should fix your problem

That sounds like the switch is failing to me. Many times these switches get wet and or dirty which causes them to fail to make a proper contact. I have sprayed many of these switches with electrical contact cleaner and seen them work like new. I would try that first before replacing the switch.

I beleive you need to change the Power Window Switches Module in the drivers side door panel, as these connections are interlinked within this module and it is usually the first part that fails. Especially that you already changed the switches & motor in the passenger door and it still does not work. Once you remove the dual switch module in the driver's side door, you will understand what I mean. Plus it is really easy to access. Good luck! I have the same model, Claude

mine does that. i just pull the switch a little harder on drivers side and it works

You'll need to remove screws that are by the door handle, arm rest, under door and side of door and then gently pull back on the panel as there will also be retaining clips attached and you don't want to break them. If needed, you can pull back the weather seal (can't reuse it, but it's not that important) and you will be able to access everything inside the door

there u should a plastic pieceinsise the car inline with the mirror remove that and there will be bolts holding the mirror on
