Steps
- Remove the wiper arms
Lift the arm caps and remove the 15mm retaining nuts. Rock each arm free from its spindle and mark its parked position before setting it aside.
- Remove the cowl panel
Release the cowl clips and separate the windshield seal from the panel. Lift the cowl clear, taking care not to damage the rubber seal or surrounding glass edge.
- Access and remove the transmission
Remove the wiper transmission mounting fasteners and disconnect the washer hose from its retaining clip. Release the headlamp and lower shroud fasteners needed for clearance, then move the shroud aside and unplug the transmission.
- Install the replacement transmission
Connect the electrical plug and position the linkage so its rubber bushing engages the vehicle guide. Refit the shroud and headlamp supports, then reinstall their fasteners and reconnect the washer hose.
- Refit the cowl and arms
Seat the cowl panel and windshield seal, then reinstall its clips. Position the wiper arms at their marked park locations, secure their nuts, and replace the protective caps.
- Check wiper operation
Run the wipers at low speed and confirm both arms sweep and park without contacting the body or each other. Correct the arm position if needed before driving.
Check your vehicle’s repair manual for exact specifications and fit.
