Steps
Mark and remove the wiper arms
Park the blades in their normal resting position and mark their locations on the glass. Remove the arm caps and retaining nuts, then lift both arms from their splined pivots.
Remove the cowl and linkage
Release the cowl clips and brackets and move the cowl away. Unplug the motor, free its harness retainer, and remove the linkage assembly from the body.
Index the replacement motor
If reusing the linkage, mark its relationship to the motor before separation. For a new motor, connect it temporarily, cycle it to park using the vehicle procedure, switch off the ignition, and disconnect it again.
Transfer the linkage and install
Separate the linkage from the old motor, align the new motor using the recorded index, and secure the linkage fasteners. Reinstall the assembly, reconnect the harness, and restore its wiring retainer.
Reinstall the cowl and arms
Align the cowl and weatherstrip, engage its clips and brackets, and reinstall the wiper arms on the windshield marks. Tighten their nuts to the vehicle specification and refit the caps.
Test sweep and park
Close the hood and test every wiper speed and the park function with the glass wet. Confirm the arms follow the correct path and do not contact trim or each other.
Check your vehicle’s repair manual for exact specifications and fit.
