Ford E5TZ-17664-B Motor And Pump Assembly

To service the front washer, start by unlocking the electrical connector tabs with a small screwdriver and unplugging the washer pump electrical connector. For models from 2001 onward, remove the air cleaner. Next, take out the two screws that secure the washer reservoir and pump motor assembly to the fender well; note that on later models, the windshield washer reservoir and coolant recovery tank are combined. Lift the washer reservoir and disconnect the small hose at its base, covering the end to prevent fluid spillage, then remove the reservoir. Drain the washer fluid into a clean container for potential reuse. Use a small screwdriver to carefully pry out the retaining ring that holds the pump motor in place, then grasp the wall surrounding the electrical terminal with pliers and pull the motor, seal, and impeller assembly out. If the impeller and seal separate from the motor, they can be reassembled. Clean the reservoir with water and inspect it for any debris. Before installing an old motor into a new reservoir, check the pump chamber and clean it if needed. Lubricate the outer surface of the seal with powdered graphite for easier installation, align the small projection on the motor end cap with the slot in the reservoir, and push it in until the seal is seated. Secure the retaining ring against the motor and plate using a 1-inch 12-point socket, then connect the hose to the reservoir fitting. Install the reservoir in the engine compartment, secure it with screws, and reconnect the electrical connector. Ensure the pump is not operated without fluid in the reservoir to avoid damage, then fill the reservoir, operate the pump, and check for leaks. For the rear washer, applicable only to models from 1991 to 1996, remove the quarter trim panel from the driver's side of the cargo area, disconnect the filler hose and electrical connector from the pump motor, pour the fluid into a container, and disconnect the discharge hose before removing the reservoir. Carefully pry the pump out of the reservoir, remove the seal and filter, and during installation, lubricate the inside of the seal with soapy water before pushing the pump in securely. Fill the reservoir slowly to avoid trapping air in the system, and do not operate the washers without fluid.

The windshield wiper/washer system on vehicles includes a motor with dual speed capabilities and optional interval operations, linkages that convert rotary motion to oscillating movement at the blades, and the wiper blades themselves. The washer system is managed by a plastic reservoir with a pump that distributes washing fluid to nozzles on each side of the windshield, with early models controlled by a single dash-mounted switch and later models by a multi-function switch. To replace the wiper arm, raise the blade end off the windshield, move the slide latch away from the pivot shaft, and pull the arm off without tools. Reinstall by holding the arm head on the pivot shaft and ensuring the motor is in the parked position. For motor removal, disconnect the negative battery cable, remove the wiper arm and blade assemblies, lift the cowl grille, disconnect the washer nozzle hose, and remove the linkage and motor wiring connector before taking out the motor. The pivot shaft and linkage can be serviced separately after removing the pivot body-to-cowl screws. For early models, the wiper control switch can be accessed by removing the switch knob and bezel, while later models use a multifunction switch. The wiper control module, if equipped, is located behind the glove box and can be removed after disconnecting the battery. The washer reservoir and pump are found on the left inner fenderwell; to replace them, remove retaining screws and the wiring connector, then pry out the retaining ring and pull the pump from the reservoir, ensuring proper reassembly with lubrication and alignment during installation.
