Hello Joe,

This could be the Body Control Module going bad and/or an issue with the Key FOB.
It will need to be scanned to confirm. I highly recommend a trip to the dealer to determine cause.

Best regards,

First, you must establish what the issue is:

1. Check for supply voltage to the actuator switch. If there is voltage TO the switch, activate the switch, and test for voltage on the switch output. If there is no voltage to to the switch, trace the issue back to the fuse panel. If there is voltage at the switch input AND voltage at the output of the switch, continue...
2. Is the vehicle equipped with an "express" automatic window mode? If so, check to be sure the microswitch on the regulator is functioning. Also, verify that the automatic module (located in the armrest) is operating. Continue...
3. When the actuator switch is operated, check for voltage at the motor. If there is voltage at the motor, make sure that the regulator mechanism is not jammed. (Has it been lubricated in the past 10 years?) Continue...
4. If the actuator is operating and the regulator mechanism is operating correctly but the power window still does not work, replace the window motor.

yes it can stop the motor from running. it is located under the intake malifold between the cylinder heads

the switch goes threw both window switches to complete the circuit so sounds like the water fried the switch

ebay

can you hear motor when switch is pressed if not check switch ,the motor sits in a regulator that controls the windows movement,you need to remove the door trim to get to the regulator which holds the motor,if you have very limited skill i wouldnt attempt it through trying to save money,

driver side switch is not working replace it
