I tried to search the forum to see if anyone had this kind of problem before, but no luck.
It just happened today. As you may know, the window goes up ~1/4" into the rubber groove after the door is fully closed. My passenger side window is stuck at that position. I tried to lower the window, but nothing happened except some clicking sound. Now, If I just close the door as before, the window will hit the top frame.
How big is the chance that the motor is broken? Any other possibilities? Thanks

Good luck!

 

And if you need a new one and can wait for shipping:

$145 after core charge.

 

The Conditional probability convinced me to order a new motor. Thanks

 

How is this brand compared to the OEM one?

Try doing the cleaning fix, and you'll have one in case you need it further down the road.
