Expert:  Chad Farhat replied 3 months ago.

may I ask if you confirmed that window motor is working, did you unplug it and gave power straight to it, does it work ?

do you V6 3.7 l or v8 4.7 liter or v8 5.7 liter, so i can look up the wiring circuit diagram ?

was the switch & door module new or used parts ?

have you tested ground & power coming out of the switch or getting to the switch ?

Please let me know

Thank You
