I can hear the pass window switch clicking and the module clicking do u think the new motor is bad?
Expert:  Chad Farhat replied 3 months ago.
I m suspecting that is the case we can confirm by applying power to it straight unplug the connector and apply 12 volts and ground you can do that if you have like a power probe tool or you can use a battery and some wires and alligator clips

we need to check the harness between the inside cabin and the driver door , for any break in the wires, i think we missing a ground

you need to disconnect and unwrap the harness cover and look thru the bundle .
