rear window motor stuck

[tdub]

I dug in pretty deep to the tailgate issue. I lubed all the moving parts, and I also lubricated the key hole, which made the key switch work 100% of the time. I pulled the face off the driver's switch and found that it was working, but not making connection. I found this out when I reached in with an object to depress the switch. BAM the rear window worked from the driver's switch!

Then the object slipped, and because I wasn't thinking when i grabbed the object I was reminded of it's metalic properties when it made contact and shorted the motor out. Unfurtunately the window is stuck down, any body know how I can manually raise the window? Someone said they gingerly lifted with a buddy until the motor caught, but I know the motor is shot now, any help?

are you for sure the motor is out, did u hook up a multi-meter to it and test it, if you hit the switch do the lights dim, oops i ment the key turn it and see if the lights dim at all if you hold it to roll the window up.

I can't get to the back motor with a multimeter. I'm getting power through the switch. When I use the key to make it go down the lights dim, when I use the key to go up nothing. I can also hear the motor engage to go down, but not to go up. I know in some power door lock actuators there are diodes contolling the flow of the current, I think i screwed one of those up, but I still cant get to the motor until I get the window up, the window is ALL the way down.

There are no diodes, it is a DC motor and you control the direction by reversing the voltage to it. Here is a diagram to help you troubleshoot the problem. An easy check to see if the motor is dead is to use a set of jumper leads, (long ones), strait from the battery (-) and (+) to the leads going to the motor, reversing the leads reverses the motor, that is all the switches do. Also note that there are two fuses involved, one for the driver dash switch and one for the key switch. If it is the motor and the window is stuck down, the easiest thing to do is remove the bolts holding the window to the regulator and move it up by hand out of the way. Be sure to support the window while it is up with tail gate door down. If you decide to remove the window, you need to remove the window weather stripping, (easier said than done without destroying it), and the seals on either side of the window, (one *****).

Good luck,

take the access panel off either A hit the motor with a hammer a couple times while someone is holding the switch to go up or B hit really hard in the area of the motor hard while someone is holding the switch to roll up. the teeth on the inside get stuck and i had to do this to my tailgate, and both doors.trust me it will work.

seabronc you are a genuis! I have an amp in the back so I just pulled the current of there instead of running a lead to the batter, used some speaker wire and got the window up!!! I actually saved your diagram to my desk top weeks ago when I started in on this window mess. This whole time it's been the stupid switch. I think I just fried that. nothing 27 bucks on jbg cant fix. much relieved, I hated leaving the window down. I've had a car (the same one) stolen twice. Thanks again seabronc!

It was the switch. The contact sucked. But on the bright side I met some locals who were able to point me to a junk yard. I'm a little new to the California "used parts" area, coming from oklahoma junk yards were plentiful... not the case here. A guy at Kragen offered me a free part he'd "picked" up at the junk yard. So it was an over all beneficial experience. Thanks for the suggestions. I even tried hitting it to make the gate work. Got the new switch on and roled down then up. It was glorious.
