Thanks for the reply Dokta. I believe that the connector is still original (I think it's a circular white plug with one flat side??), I'll get the door panel off and remove the element and check the rod adjustment. The only thing that still puzzles me is why there are problems on the passenger side if the source of the problem is the driver's side element (or its connection.) Is it possible that there is a controller or relay somewhere that got fried during the uninstallation/reinstallation?
