Steps
Mark and remove the wiper arms
Use tape to mark each blade's parked position on the windshield. Remove the arm caps and 14mm nuts, then lift the arms from their splined shafts.
Remove the cowl cover
Open the hood, move the weather seal, and release the plastic retainers. Lift the cowl cover away and disconnect the washer hose coupler.
Remove the cowl and transmission
Apply penetrant to corroded cowl fasteners, then remove the side and center bolts. Lift the cowl out, unplug the transmission, remove its six mounting bolts, and withdraw the assembly.
Install the replacement transmission
Engage the rubber mount with the firewall and position the new transmission. Install its mounting bolts and reconnect the electrical plug, then refit the side cowl covers.
Reinstall the cowl and arms
Position the cowl and reinstall its side and center bolts. Reconnect the washer hose, fit the cowl cover and seal, then align each wiper arm with its tape mark and secure it.
Test the wipers
Operate the wipers at low speed and confirm both sweep and park without contacting each other or the cowl. Adjust the arm positions if needed.
Check your vehicle’s repair manual for exact specifications and fit.
