Removal & Installation



Wiper Motor
  1. Mark the position of the wiper arms on the windshield.
  2.  
  3. Lift the caps from the wiper arm nuts. Loosen, but not fully remove the nuts. Gently rock the wiper arm back and forth and pull it from the shaft. Once loose, remove the nut and the arm.
  4.  
  5. Disconnect the negative battery cable.
  6.  
  7. Remove the air intake cowl grill.
  8.  
  9. Remove the nut that secures the inboard end of the front wiper module bracket to the stud in the cowl plenum.
  10.  
  11. Remove the two screws that secure the module bracket to the cowl plenum.
  12.  
  13. Disconnect the wire harness connector from the connector for the front wiper motor.
  14.  
  15. Remove the wiper module from the cowl plenum as a unit.
    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.

  16.  
  17. Disengage the socket bushing of the right 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.
  18.  
  19. Disengage the sleeve bushing of the left 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 sleeve unsnaps from the ball.
    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.

  20.  
  21. Use large channel-lock pliers to grasp and rotate the wiper motor crank arm so that it is positioned parallel to the axis of the wiper motor armature and the ball stud on the crank arm is at approximately its furthest point from the motor, as illustrated.

To install:

  1. Use large channel-lock pliers to grasp and rotate the front wiper motor crank arm so that it is positioned parallel to the axis of the wiper motor armature and the ball stud on the crank arm is at approximately its furthest point from the motor, as illustrated.
  2.  
  3. Position the wiper motor and crank arm as a unit onto the motor mounting bracket of the front wiper module.
  4.  
  5. Install and tighten the three screws that secure the motor to the bracket. Tighten the screws to 48 inch lbs. (5.5 Nm).
  6.  
  7. Position the sleeve bushing of the left wiper drive link onto the ball stud on the end of the motor crank arm. Place a short 19 millimeter or 3 / 4 inch 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.

  9. Position the socket bushing of the right wiper drive link over the ball stud on the crank arm. Place a short 19 millimeter or 3 / 4 inch 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.
