1985 GMC Van V8 Two Wheel Drive Automatic 100, 00 miles
I have a 1985 GMC Vandura 2500.350 V8
I have intermitent window wipers. With the arm on and signals on the wheel colume.
The intermitent swicth works however when I shut them off they still wipe about every mimute just once. Any ideas of what to look for?
