More Power Window Questions

[Captquegg]

My driver's side power window doesn't work. It quit working after a car wash.

In testing the voltage at the motor, I'm getting the correct power as long as I ground one side of the motor manually. So thinking I have a corroded ground wire I manually grounded the black wire at the switch to make sure it was grounded, but still nothing. So it looks like the switch is bad?

Thanks.

use the voltemeter and check yor switch.

I tested at the bottom of the switch and got the same results so I'm feeling pretty good it's the switch. Let me know if I'm reading it right.

The ground going into the switch is fine and when I test across either of the left window powers (up or down) and the good ground and activate the switch I get the proper voltage, but nothing just hooking to the two powers like it should. Looks like the switch isn't providing the ground like it should.

As a side note, the passenger window works fine.

Thanks for the help.

In case anyone has the same problem I wanted to post my result...

It is fixed, but both the motor and switch were bad. One must have caused the other to fail - a short or something. Alone, neither the new switch or the new motor worked, but when I put both in it was fine.

And yet more questions!

I noticed the other day that the passenger side window is a little sssllllooowww and hesitates briefly on the way down. It hardly ever gets used.

Don't think the window mechanism or guides have ever been lubricated. Is this the fix, or am I into an electrical problem?

Moving the window up and down repeatedly does seem to help to 'loosen' it up.

Any thoughts?

I have noticed the same thing. If it is raining or the window is wet it goes up/down no problem. Have been trying to think of some way to lubricate it that won't smear on the glass.

Hi Big Dave,

Think it might be more advisable to consider lubricating the moving parts and worm gear in the motor (assuming that is what drives the winding mechanism). That is what I was wondering about.

The 'welt' moulding (outside) next to the glass is not meant to be lubricated for the reason you stated. It's purpose is to act as a shield to dirt and debris that might find it's way into the door. I think the glass is 'floating' meaning that it doesn't ride up and down in channels at either end of the door frame. It's usually attached physically with an anchor at the bottom of the glass that in turn is connected to the mechanism (a scissor joint with two arms).

Sounds like it might be a Saturday maintenance item. I wonder if anyone has done this 'routine service' on the power windows yet...or if it is an electrical problem with the wiring in the channels under the door step plate.

Thanks for contributing...
