Preparation

Park the vehicle on a level surface and turn off the ignition.
Pull the wiper arms away from the windshield until they lock in the service position (perpendicular to the windshield).

Procedure

1
Remove driver side wiper blade
Locate the release tab on the wiper blade connector where it meets the wiper arm hook. Press or lift the release tab (typically a small plastic lever on the underside of the connector) while sliding the wiper blade assembly downward along the hook arm to disengage it. The blade should slide off the J-hook style arm. Support the wiper arm to prevent it from contacting the windshield.
2
Remove passenger side wiper blade
Repeat the same release procedure for the passenger side wiper blade. Press the release tab on the connector and slide the blade assembly downward off the wiper arm hook. Set both old blades aside for disposal.
3
Install new driver side wiper blade
Take the new driver side wiper blade assembly and align the connector channel with the J-hook on the wiper arm. Slide the blade upward onto the hook until you hear or feel a distinct click indicating the locking tab has engaged. Gently tug the blade to confirm it is securely locked to the arm.
4
Install new passenger side wiper blade
Install the new passenger side wiper blade using the same method. Slide the connector onto the wiper arm hook until it clicks into place, then verify the connection is secure by tugging gently on the blade.
5
Return wiper arms to rest position
Carefully lower both wiper arms back down to their rest position against the windshield. Ensure the blades make full contact with the glass along their entire length and are not twisted or misaligned.

Reassembly

No disassembly was required for this procedure.

Verification

Turn the ignition to the accessory position and activate the windshield wipers through all speed settings to confirm smooth operation without chattering or skipping.
Spray washer fluid and verify the new blades clear the windshield completely without streaking across the full wipe area.
Visually inspect both blades to ensure they remain securely attached to the wiper arms during operation.
