I got a 2000 Mercury Sable for my mom about a week ago, I was gonna do some maintenance on it before giving it too her, There is a problem with the power windows, none of the windows work, I downloaded a wiring diagram, the Master switch has a LT-Blue/BLK wire that according to the diagram should have 12v on it, I used my multimeter and it appears that it doesn't have voltage on that wire at the switch, I checked for continuity at the switch to the big connector near the door hinges, it had continuity, I checked at the Fuse Panel and somewhere between there and the connector, the LT-Blue/BLK wire is either broken or there is a relay or something that is not completing the circuit.
I have used a jumper from the battery to the LT-Blue/BLK at the switch and I can run the back windows up and down, but the front switches still didn't work. The Master Switch did have 2 connectors (Perhaps 1 for front and 1 for back, separate?).
I did noticed when pressing the One Touch down, that the #2 Relay does make a noise tho.
have the same problem?
