Windshield Wiper Blade
Replacement
Windshield wiper blades should be inspected for
wear or cracking. See Owner Checks and Services
on page 469.
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 Normal Maintenance Replacement Parts
on page 476.
To replace the wiper blade assembly, do the
following:
1. Turn the ignition to ON 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’s side blade will be
straight up and down on the windshield.
3. Pull the windshield wiper assembly away from
the windshield.
