This is an AC Delco (GM Original Equipment) Wiper Motor Pulse Board Kit. It regulates the wiper motor and all functions of the wiper and washer system.
All wiper and washer functions pass through the circuit board and connector of this module.
It is attached to the bottom of the windshield wiper motor, forward of the windshield, under the cowl.
The kit is complete with new screws and torque specs on the included instruction sheet.
I am shocked at the price increase on this part in the last 6 months. I have not found an aftermarket replacement part, so we are locked into using the GM / AC Delco part number.
