Hello, before replacing the power window regulator, always check to see if the window motor or the regulator is the problem. Turn the ignition key ON and listen for the window motor,if the window motor can be heard when you move the switch and the window does not move, the regulator is definitely bad, and if the motor does not work, the motor is the problem.This is a common problem for the window regulators to go bad. The cable is probably fine but the plastic piece that the cable locks into i bet is broken. These are not replaceable you will have to replace the whole regulator. Beware of aftermarket ones they are not as good as OEM but they are very expensive at the dealer probably about 250.00 to 300.00 dollars.

Thanks

Power Window Motor: Service and Repair
REMOVAL
1. Disconnect and isolate the battery negative cable.
2. Remove the window regulator from the door.
3. Place the window regulator on a suitable work surface and remove the screws that secure the power window motor to the window regulator.
4. Remove the power window motor from the window regulator.
INSTALLATION
1. Position the power window motor onto the window regulator.
2. Install and tighten the screws that secure the power window motor to the window regulator. Tighten the screws to 9 Nm (80 in. lbs.).
3. Install the window regulator onto the door.
4. Reconnect the battery negative cable.

The window regulator and/or window motor is getting bad. Mine did the same thing and I replaced the motor and it still ran slow, then replace the regulator and now it works great!

The power window regulator and motor come as am assembly. Usually the cable snaps and the window drops down and won't come back up. About a $400 repair.
------------------------------------------------------------------------------------------

1. Remove the front window regulator.
   • Loosen the two hanger bolts.
   • Remove the front window regulator bolts and front top run channel bolt.
