how do you replace the wiper motor pulse board on a 1999 Chevy Silverado 2500
I have found that most S10 (GM) wiper motor trouble is caused by a faulty pulse board, not the motor itself. It is easy to replace and your local auto parts store can sell you an aftermarket pulse board for aprox $20. The wiper motor does not have to be removed to change the pulse board. Unplug the wire harness from the motor, remove the three small screws holding the cover to expose the pulse board then wiggle the board straight out. Reverse order to install.
