i have a 1993 ford mustang 2 door the passager window rolls up and down but the drivers side does not how do i know if its the motor or the regulator i cant hear the motor running
....am suggesting the wiring harness on the driver's side has flex-flex-flex until it becomes an open circuit...either that or you could pop out the switch block and see if the switch still operates normally....okay here's a few choices for the wiring harness...the switch is too friggin' easy...harness...not so much so...have your nephew do this job~
If you don't hear the motor running, I'd say you be replacing that. Open the door panel up and see.
