Wiper Motor

WARNING
Do not apply pressure to, or pry on, the plastic drive link bushings. When removing a drive link from, or installing a drive link onto the ball stud on the wiper motor crank arm, apply pressure to, or pry on, only the metal portions of the drive link around the bushing. If the bushing is damaged, the entire front wiper module MUST be replaced.


WARNING
Do not remove the crank arm nut from the wiper motor output shaft. The crank arm is indexed to the output shaft with the motor in the park position during the manufacturing process, but there are no provisions made for correctly indexing this connection in the field. If the crank arm to output shaft indexing is incorrect, the entire front wiper motor and crank arm unit MUST be replaced.

  1. Disconnect and isolate the battery negative cable.
  2.  
  3. Remove the front wiper module from the cowl plenum and place it on a suitable work surface.
  4.  
  5. Disengage the socket bushing of the wiper drive link from the ball stud on the wiper motor crank arm using two large screwdrivers, one on each side of the ball stud. Pry between the crank arm and the metal portion of the drive link until the socket unsnaps from the ball.
  6.  
  7. Remove the three screws that secure the wiper motor to the motor mounting bracket of the wiper module.
  8.  
  9. Remove the wiper motor and crank arm as a unit from the motor mounting bracket of the wiper module.

  4.  
  5. Position the socket bushing of the wiper drive link over the ball stud on the crank arm. Place a short 3 / 4 inch or 19 millimeter socket over the bushing as an installation tool. Then use large channel-lock pliers to apply enough pressure to the underside of the crank arm and the top of the socket to snap the bushing onto the ball stud. Do not apply pressure directly to the plastic bushing.
