Hey all, I know this is a common issue with the late 90`s trucks, but my 03 has come down with a similar wiper power issue. Mine had some funny movements on delay, then switch to low constantly without delay and now wont even shut off at all. I can switch to high but I cannot shut them off without pulling the fuse. I thought GM rectified the board problem within the early 2000 models but I`m wondering if that recall should have moved further up the years. Any suggestions other than the board being bad? Maybe the combo switch this time? Any info or suggestion would be very helpful with winter breathing down on my neck.
