i've searched and found out about bad grounds and pulse boards for 2nd gens. i found its a bad ground cause i took a jumper wire and connect the neg. terminal of my battery to the housing of the wiper motor and it works. i read somewhere as to which ground wire was usually the problem, but i can't find that thread again. i wanna say its somewhere near the headlights, but not sure which side. i have an extra wiper motor from another truck if all else fails. thanks for any help.
