97 GMC Guy
Newbie
Bought the truck 6 months ago. Had one speed on wipers...high. Just today replaced pulse board.wipers now work with intermittent, high and low, but won't turn off. The switch is on the turn signal. Looking at the fixed marker the marks are not sequenced with the function. In other words when it points to off the wipers are still on the lowest intermittent setting and will not shut off. The replacement assembly for this truck is $160. Any help avoiding replacing the unit would be greatly appreciated.
