You will need to remove the Panel & the Regulator to check the problem
It takes a certain amount of special tools & if you have not done this before, then you may want to seek someone local to do this.
Voltage & Ground needs to be checked at Window Motor to confirm the Ground & Voltage is reversing
Use of a VOM is needed to test
The way it works:
Switch held in Up position
One wire will have 12 Volts +
One wire will have Ground -
Switch held in Down position
The wire that had 12 Volts + is now Ground -
The wire that was Ground - is now 12 Volts +
If Voltage or Ground checks good at motor, replace motor.
If Voltage or Ground does not check good:
Check Switch Voltage & Ground.
Check for broken wires at Door / Kick Panel Boot
