Open the engine hood and, working at the right rear of the engine compartment, siphon out washer fluid from the reservoir. For the washer fluid level switch replacement, detach the electrical connector and carefully pry the sensor out of the reservoir, being prepared to catch any dripping fluid. For the headlight washer pump replacement, detach the electrical connector, cut or loosen the hose clamp, and detach the hose from the pump before carefully prying the pump out of the reservoir, again being prepared for dripping fluid. When replacing the rear window washer pump or windshield washer pump, detach and lift the reservoir forward, detach the electrical connector, cut or loosen the hose clamp, and detach the hose from the pump, then carefully pry the pump out of the reservoir while catching any dripping fluid. Installation is the reverse of removal, ensuring to coat the grommet at the base of the pump or sensor with an anti-friction agent, use new hose clamps, check that fluid hoses are not kinked after installation, fill the reservoir, and check for leaks.
