Power window malfunctioning

Hi,

When you try to move the window, are there any noises? Can you hear the motor running or something grinding? Do the other windows work? If you try helping it up, will it move?

Sorry for so many questions. There are a lot of different possibilities. However, since it is trying to move, if there are no sounds associated, most likely the motor is bad.

Let me know.
Joe

Hi,

I just watched the video. I suspect the window regulator is bad. If you watch. The one edge of the window moves and the front portion doesn't. The regulator is either broken or something has come apart.

Take a look at the attached pic. It shows the regulator. I highlighted the component I'm referring to. If you want, I can provide directions for removal and replacement. It's a bit tedious to do, but we can give it a try if you want.

Let me know.

Joe

Hi,

You are very welcome. Listen, I have directions for removal and replacement, but it is part of an entire door overhaul. So, it starts with removal of the door panel and so on. I will stop at the end of the regulator removal. Before you purchase the regulator, remove the panel so you can see in where the door is attached to the regulator. There are two bolts that hold it to the regulator track. Make sure one hasn't come loose and is causing the window to jam.

I hope this helps. Let me know how things work out or if you need help. Remember, before purchasing a new regulator, make sure none of the track has come loose causing the glass to bind.

Take care,
Joe

You are very welcome. Did you get it repaired?
