Need help diagnosing my windows.

[RefinedThinking]

Okay so my RR window only works with the front switch. It does not go up or down when using the rear switch. I am using known good switches because Ive been switching them around to make sure. This is my wiring diagram.

Is that little square button off to the right on the center counsel up or down?

Something simple /shrug

It's not the kill switch. Thanks for the response though.

So when you used the other side rear switch, still no workie? I do not know for certain, but I think those are rear-specific switches, maybe check RealOEM.com to make sure.

Blue/green and black/yellow should show a solid ground on them until the "up" or "down" command switches one of them to +12V. I see you show the +12V, but are both motor wires a solid ground (don't you dare use a DVM to test either) when both switches are at rest?

When both switches are at rest there's 12v all the way through. When I use the front switch to lower or raise the rear window there is a voltage drop. But when I use the rear switch both stay at 12v.

Have you pulled the rear door window wiring harness and checked everything for continuity? You could have a short somewhere in that harness right where it meets up with the rear window switch....

Yeah I even took the connector out and hooked the wires directly to the switch.

OK, that is an issue.

As I said, test for ground on those wires. They should show a ground all the way through, until one is in use.

The ground comes from the front switch, just as it shows in the diagram.

I did some digging and discovered someone previous did some crazy wiring. They had something else wired into the rear kill switch.. Now I have to try to clean up this mess. Thanks for the help though stereoinstaller.

Check that front ground point, if someone was monkeying in there, it could be wrong or loose or whatever...good luck!
