Windshield Wiper Blade
Replacement
Windshield wiper blades should be inspected for wear
or cracking. See Owner Checks and Services on
page 6-10.
It is a good idea to clean or replace the wiper blade
assembly on a regular basis or when worn. For proper
windshield wiper blade length and type, see
Maintenance Replacement Parts on page 6-16.
To replace the wiper blade assembly:
1. Turn the ignition to ON/RUN with the engine off.
2. Turn on the windshield wipers and turn them
off again when the wipers are in the out-wipe
position. The driver side blade will be straight up
and down on the windshield.
3. Pull the windshield wiper assembly away from the
windshield.
