To remove the washer reservoir and pump for 2007 and earlier models, open the hood and take out the securing bolt for the washer bottle filler neck, then pull the filler neck up to disengage it from the reservoir. Apply the parking brake, loosen the left-hand front wheel nuts, jack up the front of the car, and support it on axle stands before removing the front wheel. Remove the retaining screws and release the fender well liner for access to the reservoir; on 2005 models, also remove the drive bell splash shield and set aside the air-conditioning accumulator to access the bolts securing the washer bottle. Unscrew the mounting bolts and slide the reservoir forward to release it from the inner fender panel, then disconnect the washer hoses and wiring connector from the washer pump while anticipating some fluid loss. Pull the windshield washer pump and, if applicable, the headlight washer pump from the reservoir, and check the rubber seal/filler for damage. For 2008 and later models, remove the upper washer reservoir mounting screw, move the engine coolant reservoir out of the way, raise the vehicle securely on jackstands, and remove the lower air deflector. Disconnect the wiring from the washer pump, detach the hose, drain the reservoir into a container, and then remove the mounting nut and screws to take out the washer reservoir and pump assembly. For the windshield washer jet, with the hood open, disconnect the washer tube from the bottom of the jet and, if necessary, disconnect the wiring for the jet heater before carefully prying the jet out from the hood. For Hatchback and Wagon models, remove the high-level brake-light unit by undoing the securing screws, pull the washer tube from the jet, and check with a dealer about the availability of the washer jet separately from the rear light lens. For the headlight washer jet, remove the front bumper, disconnect the washer tube from the base of the jet, and withdraw the jet from the bumper after removing the retaining clip or screw. Installation is the reverse of removal, ensuring that the window washer jets are pressed in firmly, the front bumper is reinstalled after the headlight washer jet, and the grommet is lubricated with a water-based lubricant when reinstalling the washer reservoir.

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.

Install the reservoir in the engine compartment and secure it with the two screws.
