  Q: How to replace Washer Pump,Washer Reservoir,Wiper Motor and Wiper Switch on Ford F-250?

  A: 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.
