Steps
Mark and remove the wiper arms
Mark each blade's resting point on the windshield with tape. Remove the arm caps and nuts, then rock the arms free of their splined pivots.
Remove the hood cowl
Open the hood, release the cowl side clips, and lift the panel tabs from the windshield edge. Set the cowl aside without bending its plastic retainers.
Remove the wiper transmission
Unplug the wiper motor and remove the transmission mounting bolts. Slide the assembly off its locating pin and lift it out of the engine bay.
Transfer the motor to the replacement
Remove the motor fasteners and separate the motor from the old linkage. Attach it to the replacement transmission and secure the crank and lock hardware correctly.
Install and park the transmission
Place the assembly in position, reconnect the motor, and secure its mounting bolts. Cycle the wipers once to establish park, then switch them off before fitting the arms.
Reinstall cowl and wiper arms
Hook the cowl under the windshield edge and press in its retainers. Align the driver and passenger arms to their tape marks, tighten the nuts to specification, and test operation.
Check your vehicle’s repair manual for exact specifications and fit.
