Only the drivers window worked when I bought my burb. I ordered new regulators for the other three. That fixed both passenger windows, but the rear driver side didn't work. I figured it was the switch so I bought a new one. Still nothing! I know the plug is getting power to it. Any ideas?

 

Are you sure the regulator is good? Check all wires in the flexible conduit that is in the door jam. You may have power but no ground. You may also have problems with the master switch at the driver's front door.
