Get started by removing the wire harness connector from the motor connector receptacle. Following that, unplug the supply hose from the pump/motor outlet, so the washer fluid empties into a clean vessel for reusing. In case that switch exists, take the washer fluid level switch vent hose off the barbed vent nipple on the washer pump/motor unit. Grab the washer pump and carefully remove it from its seal in the rubber grommet of the reservoir, being careful with the reservoir. Pull and remove the rubber grommet sealing the washer pump mounting hole on the reservoir. Replacing the washer pump is done by putting a new grommet seal into the mounting hole, making sure it isn't used. Line up the end of the pipe extending from the washer pump with the rubber ring in the reservoir and push firmly down until the pipe is joined. If you have a washer fluid level switch vent hose, reinstall it onto the barbed vent nipple found at the top of the washer pump/motor housing. Attach the washer hose to the nipple coming out of the pump and slot the connector portion of the wire harness onto the motor connector receptacle. After removing the reservoir cap, add the washer fluid you saved from before.
