The rear wiper blade is a Chevrolet-only part so you'll need to go to the dealer to get a replacement (no aftermarket options available to my knowledge). When at the dealer, ask for the replacement procedure.
The front wiper blades ARE available in aftermarket options. See sources and related links below for a list of correct attaching and length wiper blade options.
Raise the wiper blade and hold. Pull the release on the bottom of the blade and wiggle it off.
Replace wiper blade and carefully bend wiper arm so it makes good contact with windshield
stick the wiper blade up your hole - I can't figure it out either.
How do I replace the windshield wiper switch?
You take it to autozone and they will show you
See Windshield Wiper Blade Replacement on page 6-40 of your "Owner's Manual", under Section 6: Service and Appearance Care.....
There is a tab you pull up on located at the top of the blade. When you pull it up the wiper should be able to slide off the wiper arm pin, replace with a universial blade.
The wiper blade misses the windshield in the middle of the wipe. Is there an adjustment for that ? I have replaced the wiper to no avail.
are you serious... life blade off windshield, unclip plastic fastener off the center of the wiper arm, remove wiper, replace in reverse order.
Turn the wiper switch to the on position. Turn the key on and as soon as the wipers go straight up then turn them off. That will make it easier to remove the blade. Lift the wiper away from the windshield while pulling down. Be sure to not let the wiper fall against the windshield. Push the new one in place and you are done.
Replace the locking tab on top of the wiper
To replace a windshield wiper motor for a 1998 F150, first remove the bottom trim on the window. Then remove both wiper blade assemblies and all screws on the metal cowling. Remove the retaining clip from the wiper motor linkage and pull the controls rods off.
