does it make any sort of 'whirring noise' when you press the button? Usually, and ive had this happen to me before, the window itself just 'falls off the track' meaning the little bar at the bottom that it sits on to be raised and lowered has somehow slipped and the window has came off of it, or the bar itself came lose from the bracket that it attaches it to the motor. pretty easy fix. sometimes you have to take off the door panel to do it/see what you're doing, but usually you can just grasp the window between both your hands, lift it up yourself and try to reseat it on the track by 'feel' so to speak. hope this helps
More than likely the regulator or motor were damaged when you tried to lower it. If the glass had moisture around the edges it would have frozen in the track, when you went to open the window the regulator probably broke under the strain. The motors generally are more durable but the regulators are often plastic and wire cable.
The window regulator has gear teeth on it that connects to a metal track attached to the window glass. The teeth are most likely stripped and the grinding noise is the motor trying to mate to the broken teeth. You need to replace the window regulator and I wouldn't hesitate to replace the motor at the same time. It's a costly fix but worth it to only have to be inside the door once and the motor will have to be removed at the same time the regulator is replaced. If you can reach the glass and pull up on it at the same time you can probably get it to roll up as a temporary fix.
Before the failure, did it make any knocking or griding noises? When you operate the button does the motor make it's normal noise? Did the window become loose and fall down inside the door abruptly? Some vehicles have issues with the "window regulator". This is the cabling device that hoists and lowers the window on the inside rail. Some automakers use plastic bits to keep the window on the rail. If those become loose or break, the window will fall off the tracks. Continued operation of the window will cause the regulator (cables, gear or motor) to fail. If you want to attempt a DIY fix, remove the door cover (a mechanic will usually call this a door card) and see if the window is off the rails. Good luck.
i would say window motor is getting weak. its the one that gets used the most. you could try to get some lubercant like wd40 in the tracks might make it move easer. but eventualy the motor will have to be replaced
What you have could be one or both of the following:
Dirty/sticky window tracks, or a window motor issue.
What I would do before you take it in: Get some 100% silicone spray, lower the window, and spray the lubricant down inside the door, on the rubber strip that the window travels in. Run the window up & down to get the lubricant worked in. See if that helps.
What is happening here is this: There is a thermister built into the drive motor, and when the motor gets a little too hot (working too hard, with dirty window rubbers), it opens, like a circuit breaker. When it cools off, the thermister contacts close, and the window works again. 2 things cause this: Dirty window run rubbers, or a motor that is beginning to fail.
Hope this helps. Feel free to comment back for more info...
