  Q: How to replace the front Wiper Pulse Module on Buick Terraza?

  A:

  To replace the Wiper Pulse Module first, we have to start by opening and supporting the hood, then take the driver side Wiper Arm and the passenger side Wiper Arm. Next, remove the air inlet grille panel and install the washer container into the engine room. Pull the electrical connector off from the Wiper Motor and take off the 4 bolts from the Wiper Pulse Module. Do it carefully, pull the passenger side module first out from the opening of the front plenum, and then from the driver side fender flange opening, and extract it from the vehicle. For installation, place the Wiper Pulse Module into the lower plenum in the driver side fender flange opening and then rotate the module into the opening at the passenger side plenum, making sure the rear center mount is secured into the sheet metal flange at the rear of the module. Mount the Wiper Pulse Module bolts then tighten them in a sequence at 10 n.m (89 lb in). Connect the electrical connector to the motor, then replace the air inlet grille panel, then install the driver side Wiper Arm and passenger side Wiper Arm. Lock the washer container and close the hood, then check the wiper system for correct function.
