Pablocruise. outstanding info. for trouble-shooting the deadly rear window on the "Little Piggies" Helped out tremendously getting the window to work. Recently purchased 1978 PIG with a defunct rear window. Traced all the wiring and due to the PO heavy off-roading the cargo side walls were full of mud and the ground wire for the rear-window safety switch was not making contact. Thoroughly cleaned all connections and now works perfectly.
