So, a 1992 300e 2.6. RR power window does not respond to either switch, on the door or from the center console. No noise at all. Got the door panel off expecting a broken regulator or bad motor. Took leads from motor, hooked to 12v, up and down with no problems at all? All other windows are fine. What am I looking at here, broken wiring somewhere, fuse to check? I figured all windows would be on one fuse, but maybe not? Both switches bad possibly?
