I can't find anything with the search tool but I need to know if anyone knows how to test the sunroof motor? There appears top be 3 plugs going in, one has power all the time but which pins should have power with the switch and which ones can I put power to to test the motor? It is a 87 560 SEC It has new tracks or angular arms or what ever they are called and supposedly the motor has been rebuilt but I can't even get a sqeak out of it when I hit the switch.

They tend to get a "Whitish" corrosion product,where the Points contact the
"Keepers".[If the Metallic fuse part is not cracked Microscopically,by now.]

I don't have the Wiring Diagram for that Chassis...
Hopefully some helpful webizen will chime in with it.

You do have P.M. traffic

Compress are you referring to the motor?

Not sure what that diagram is telling me, pretty small. Can someone simply tell me what wires should be live when the switch is activated?
