Hello,

1993 Chevy G30. Recently my driver and passenger side power windows won't operate. I've verified that power is getting to the switch and have replaced the switch. I'm wondering if anyone knows the wire path between windows. Does the ground for the drivers side window terminate at the passenger side? If the driver side window motor is completely dead, would that be the reason the passenger side is also not working because some sort of break in the chain? Assuming they are wired together to share the same fuse.

Any help/experience on this would be helpful.

Thanks!

 

there should be a ground at each side.
Try testing the motors by applying 12V directly to them.
Common culprits are wires breaking in the door harness where they constantly bend back and forth.
