Remove wiper motor and linkage from the wiper drive system module, which must be removed as an assembly. Disconnect negative battery cable. Remove wiper arms. Raise hood. Remove screws securing lower reveal molding. Lower hood until it is open about 4". Remove lower reveal molding (pull backward and upward, toward windshield).

Raise hood. Remove screws securing air inlet panel (cowl vent screen). Remove underhood light switch (if equipped). Remove air inlet panel. Run wiper motor until crank arm is in the inner wipe position (bottom of sweep). Crank arm is in the inner wipe position when it is facing left side of vehicle.

If crank arm can be rotated to inner wipe position, go to next step. If crank arm cannot be rotated to inner wipe position, remove 3 screws securing bell crank housing near center of firewall to allow module to be removed.
