Steps
- Remove and identify the wiper arms
Lift the arm-nut covers and remove the retaining nuts. Pull the arms from their studs and note which one belongs on each side so they can be aligned correctly later.
- Remove the antenna and cowl
Remove the antenna grommet and unscrew the antenna mast. Open the hood, peel back the cowl weatherstrip, and lift the cowl panel away from the windshield base.
- Disconnect and remove the old linkage
Remove the transmission cover screws and note the linkage crank position. Remove the crank nut, detach the linkage from the motor, then remove the transmission mounting fasteners and guide the assembly out from the driver side.
- Install the replacement transmission
Feed the new assembly into position and secure its mounts. Align the linkage with the position noted earlier, reconnect it to the motor, and tighten the crank fastener to the vehicle specification.
- Restore the cowl and antenna
Seat the cowl panel and weatherstrip along the windshield, then reinstall the antenna mast and grommet. Check that the cowl does not interfere with the linkage or wiring.
- Align the arms and test the wipers
Install each wiper arm on its correct stud and align it with the windshield's parked position. Tighten the nuts to specification, refit the caps, and run the wipers through a full cycle.
Check your vehicle’s repair manual for exact specifications and fit.
