Yesterday, I had all the windows and the roof open. When I tried the all-in-one closing feature with the door key, the passenger side front window would not close. Today, I got it to close in increments of about 2in by repeatedly disconnecting the battery and reconnecting. After maybe 5 times of reconnecting the battery, getting the window to close a couple of inches more each time and then disconnecting, I got the window fully shut. Playing around with it a bit, if I attempt to open it, it will go down a couple of inches and then stop. I then have to disconnect the battery to close it again. Does anyone have a suggestion of how to get the window working properly again? It seems like this might be a switch or electronic module issue??
Thanks

Personally, I would tend not to open/close the windows any more than need be. If it were me, I would check the voltage across the front passenger side power window motor as it sort of sounds to me like that motor may be failing.

 

More likely to be the window regulator mechanism---especially if your vehicle has lived in salty winter environment. The cables can and do rust and eventually break. There are numerous threads if you use the search function.

 

Hi Rickkk. I got into it today. I think you may be right in that the motor is failing. I removed the motor from the rest of the regulator mechanism, and it will not rotate continuously even when completely unloaded. I'm hoping to find cheap replacement on ebay. Thanks Paul.

 

Surprisingly, since i live in upstate NY, the cables are not in bad conditiion. It did take a bit of a heave though to push the window up manually, which improved a bit after dousing the runners and cables with silicon spray. I'm into it now, so I'm going to get a beer and see if I can do anything with the motor, which I think may be the culprit in this case. Thanks!

 

You're more than welcome Paul. Anything to oblige.

 

Is there a place that repairs electric motors around where you live?

 

Just to finish up this thread, I got my ebay window regulator, which originated from a car with around 66,000 miles - about 95k less than mine! It was a pretty easy fit and I gave the moving parts a good shot of silicon spray before I closed everything up. The window now works well. Thanks to everyone who provided advice on this.

Paul.
