Drivers window `wont roll down (but does roll up) all other windows roll down/up
It could be the fuse, does it go down? If not chk. fuse, if fuse ok, see if you can help it down by pushing down on window wile working switch, and also same wile trying to go up, if it don't work or if its slow chanses are the motor is tired and needs replaced or its lost power like bad switch or broken wire. there is also a chanse it came off the track in witch case the door panel will have to be removed.
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.

new master switch on drivers side, less than 3 months old. I VOM'ed DS window motor, shows power to motor for rolling up but no power for down. window rolls down on a direct connetion to a power source. switch shows contact for up and down. looking for the location of the express down module.
Anybody know if its in the master switch?
can you be more specific?
It is inside the door you will need to remove the door panel to access it, don't think i can be any more specific. The part is about $100
