My tow vehicle is a 76 Suburban with a tailgate and electric rear window. Last night I discovered that the window will not lower into the tailgate. The motor engages, but the window acts like the regulator is jammed on the driver's side. Anyone have any suggestions on how to get that sucker lowered? I'm headed to the track this weekend and this will really bite if I can't access anything through the rear door. Thanks.
