Ford BB5Z-17528-FA Wiper Blade Assembly

Removal steps 1. Park on a level surface, turn off the ignition, remove the key, and set the parking brake. 2. Protect the windshield with a towel or soft cloth and, if the arm design allows, lift the wiper arm to its service position; note that some arms do not lift away from the glass. 3. Disconnect the negative battery terminal to isolate electrical systems before working near the wiper mechanism. 4. Identify the blade-to-arm attachment type (hook, pin, bayonet, push tab, or quick-release); designs vary. 5. Support the wiper arm to prevent it snapping back, then depress, lift, rotate, or slide the retaining clip or tab as required by the attachment style and remove the blade from the arm. 6. Inspect the arm, pivot, and any adapter pieces for damage, corrosion, or debris and clean contact surfaces as needed. 7. Retain any small adapters or clips from the old blade if they are required by the replacement. Installation steps 1. Confirm you have the correct replacement blade and any required adapter for the wiper arm style. 2. If the new blade uses a separate adapter, fit the adapter to the blade or arm per the adapter's design; adapter procedures vary by type. 3. Align the new blade with the arm and engage the attachment-slide, rotate, or snap it into place until the retaining mechanism is fully seated. 4. Gently lower the wiper arm back onto the windshield; always support the arm until the blade is secured to avoid glass damage. 5. Reconnect the negative battery terminal. 6. Start the vehicle and cycle the wipers (with washer fluid if available) to check sweep, contact, and parking position; look for streaking, chatter, or missed areas. 7. If performance is poor, recheck seating and arm condition, adjust or reseat the blade, and consider replacing the opposite blade for even wear. Repair tip: Replace both wiper blades at the same time for consistent performance and keep a soft towel under the arm during work to protect the glass.
