Windshield wipers won't turn off Chevy Avalanche 2003?
I have the same problem, the dealer said that it is the
windshield wiper cover, part number 88958136 (AC Delco). The cover
has the circuit board mounted in it that controls the wiper motor.
I bought on line at quite a savings, however, am trying to find out
how to get to the windshield wiper motor to change it.
