One problem related to wiper has been reported for the 1996 GMC C1500. The most recently reported issues are listed below.
My windshield wiper runs intermittently,and sometimes stops altogether or runs at full speed and will not turn off. Usually I pull over and lift the hood and give the windshield motor a thump and this seems to sort it out till the next time. The thing that annoys me most is when it wont start in traffic. My vehicle is a 1996 GMC suburban and I had resigned myself to living with this problem until I stumbled on the recall notice. I have never had any incidents or even come near with this complaint but I thought it was worthwhile to check this out?.
