how do you replace the wiper motor pulse board on a 1999 Chevy Silverado 2500
have you checked fuses and relays? Yes, I actually replaced the blower motor module & that didn't work. The Blower Motor itself spins freely & there doesn't seem to be any electrical issues. Could it be the Blower Motor speed switch??? If so, is that hard to access?
There was a recall on the windshield wiper motors. Check with your locate dealer and they may replace it for FREE!!!!
Look at the link I posted, that should help you. (:
It is attached directly to the wiper motor.
