I had myself lived dangerously with the wiper problem, opening the hood and displacing the wiper motor bundle of wires just to see it work for a limited time before I searched and found the "wiper syndrome" by JIXIX...related to his Surburban..but naturally common to a lot of GM cars. Aided with my Transport manual...that by the way has the graphic art upside down....(I edited and reversed it for the posted version) I corrected my problem in a short time, then later took a few pictures.
It is just fun to know it serves.
