SOURCE: 01 PT Cruiser window won't go up Can hear motor
sounds like he broke the regulator and it will need replaced
SOURCE: 98 corolla drivers side window won't roll down or up well
I just repaired a 1999 Corolla (160,000 miles) window regulator with the same problem. I checked the motor commutator windings for shorts and the motor was OK. The brushes were still good. The motor is built like a clock - extremely well made with almost no indication of wear. Bench testing showed that the motor would not rotate once it had been run for a few seconds.
Elsewhere on the Internet someone mentioned a PTC Thermistor. This was exactly what was causing the problem. This is a special type of resistor "in series" with the motor that increases resistance when hot. It prevents the motor from drawing much current when stalled at the top or bottom of the window travel or in event of a jam, etc. The thermistor doesn't look like a standard "Radio Shack" part. By pulling off the motor top the magnets and commutator pull out. The PTC Thermistor is the two large copper plates separated by a silver looking material about 0.001" thick that are in series with one of the brushes. To fix, short out the thermistor. I tested with a small clip of copper wire. I made a permanent fix by soldering a jumper from one plate to another. During assembly, don't break the brushes.
The power window works great! I don't need an "electronic minder" to stop power to the motor at the top or bottom of the travel; I can do that. I don't intend to place my head in the window and push the button. If you have kids, this fix might not be for you.

SOURCE: my car window wont roll up or down, it just wants to slide down and up
I have a Pontiac grand prix that my passenger rear window wont roll up, i need to get the window to close atleast temporarily until i can get the problem looked at. I have taken the door apart and tried pushing it up, but it wont go as much as i have tried. Any advise would be great right about now. thanks
