how do you replace the wiper motor pulse board on a 1999 Chevy Silverado 2500
Behind the plastic cover on the wiper motor.
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.

It is attached directly to the wiper motor. Remove the three small screws that hold a black plastic cover on the wiper motor. The pulse board is under that cover. Most of your wiper motor problems are from a faulty pulse board.
Change the pulse board in the wiper motor.There is three screws on the back cover of the wiper motor,then unplug it and it pulls out.
The electrical contacts on the pulse board are likely not making contact or are damaged in some way. You can replace the pulse board (about $25 from pep boys.), it is located on the firewall, next to the wiper motor. Actually looks like a square box adjacent to the wiper motor. You may just need to clean the electical contacts inside. They are two brass or copper pieces which make contact with a spiral wire on the circuit board. Make sure they are clean amd making contact with the circuit board.

In my experience it is rarely the wiper motor at fault, it is always a faulty pulse board. Your local auto parts store can sell you an aftermarket pulse board that will outlast the GM original. The pulse board can be easily changed without removing the wiper motor from the vehicle.
Inside the wiper motor. Easy to change without removing the wiper motor. Unplug the harness connected to the wiper motor, remove the three small screws that hold a black plastic cover on the front of the wiper motor, remove the cover, remove the pulse board. The pulse board is available from your local auto parts store.
