I push the button to put window down and just hear a click, but the window does not move. I either bang the door with my fist or open and slam the door, and then it goes down. What do you think is wrong? Answered by wikiHow Contributor
The motor might be jammed.

How do I fix a window that only moves half way? Answered by wikiHow Contributor
If they are the windows in the back, they are most likely child proof windows. In some cars, there is a switch in the door that can release the child proofing and let the windows go down all the way. Otherwise, you may have to see your local mechanic.

If your car is relatively new, take it into the dealership where you bought it to be repaired. Otherwise, have a professional mechanic repair it.

Could there be a short in the window motor if I replaced my car door, plugged in the window and the fuse blew? Answered by wikiHow Contributor
Sounds likely. I would double-check the wiring inside the door before replacing the motor, however.
