How to Change a Windshield Wiper Motor on an Expedition

If the wiper motor on your Ford Expedition fails, you could suddenly find yourself without a way to clean your windshield off during a heavy rain or winter storm. This is because the wiper motor controls the operation of the windshield wipers. If your wipers fail, it could cause a car accident due to being unable to see the road ahead of you. When your wiper motor starts to whine or squeal or strain, it's time to replace it. Purchase replacement motors for your Ford Expedition from most auto parts stores.

Things You'll Need

• Replacement wiper motor
• Socket wrench
• Socket set
• Screwdriver (Phillips head)

Instructions

1. Lift the wiper-arm assemblies away from the windshield until they lock in a vertical position.

2. Unbolt the wiper arm at the base of the arm where it connects to the wiper motor and linkage using a socket wrench.

3. Pull the wiper arms off the wiper linkage.

4. Remove the screws that hold the cowl in place around the wiper linkage and motor assembly.

5. Lift the cowl off the Expedition.

6. Unplug the electrical connector running to the wiper motor.

7. Unbolt the 3 bolts holding the wiper motor in place. Then, slide the wiper motor off the linkage and out of the Expedition.

8. Insert the replacement motor, bolt it to the linkage and the firewall, and reconnect the electrical connector. The rest of the installation is the reverse of removal.
