How to Repair the Washer Pump for a 2004 Mitsubishi Lancer

When the washer pumps fail on a 2004 Mitsubishi Lancer, the first symptom you may notice is a lack of fluid coming from the washer jets when you press the spray button. Although the pumps are durable and generally last for many years, they will need repair eventually. In order to repair a 2004 Mitsubishi Lancers washer fluid pumps, the pumps must be removed from the washer fluid reservoir and replaced; the pumps themselves are sealed, non-serviceable units.

Instructions

Removal

    1

    Loosen the lug nuts on the front, passenger-side wheel with a lug nut wrench. Raise the vehicle and set it down on jack stands. Remove the lug nuts and then remove the wheel.

    2

    Remove the screws holding the side undercover panel to the engine and splash guard, using a ratchet and metric socket. Remove the bolts holding the inner splash guard to the fender and vehicle body, using a ratchet and metric socket.

    3

    Disconnect the hoses from the washer pumps and allow the windshield washer fluid to flow into a drain pan.

    4

    Disconnect the electrical connectors on the washer motors. Remove the washer motors from the reservoir by pulling them up and out of their mounting holes. Allow any excess washer fluid to flow into the drain pan.

Installation

    5

    Set the new washer pumps into position and press them down into their mounting holes until they are fully-seated.

    6

    Reconnect the electrical connectors to both pumps and then reconnect the front and rear pump hoses. Remove the drain pan from underneath the vehicle.

    7

    Set the inner fender splash guard into position and reinstall its retaining bolts. Set the side undercover into position and reinstall its retaining screws.

    8

    Refill the reservoir and test the washer pumps. Lift the vehicle using the jack, remove the stands, and set it back down on the ground.
