Electrical 1995 right door power window switch issue

  • Sponsors (?)


It needs a new master switch if the wiring checks out and the power and grounds are there
That master switch controls the power and ground feed to the satellite switches
So, at rest, the master switch supplies the power and ground to the RH door switch
Sometimes find power on both wires, or ground on both wires, at the satellite switches when the master switch fails
 
After removing the panel to gain access to the motor wires
I reinstall the switches and run jumper cables to the door I am working on
That way I can manually fire the motor either way and can see exactly what the switches are doing (as far as switching powers and grounds like they should)
