Re: Whacked Out Wipers
On newer models (Limited trim) the wipers are automatic. As for your '99, if it's anything similar to my '02 GMC 2500, I had to replace the wiper motor itself. The relay's tested OK. It was attached to a small circuit that helped control the intermittent speed. I priced out a new board, and it was CHEAPER for me to buy a new motor with the board already installed! Before I replaced the board and wiper motor, the wipers would only work on high. others will reply shortly with suggestions.
