Headlamp Washer System

WARNING: This page is about a different car, the 2007 Dodge Sprinter. However, it is still accessible from the selected car via links, so may be relevant.

An electrically operated headlamp washer system (also known as the Headlamp Cleaning System/HCS) is optional factory-installed equipment on this vehicle. The headlamp washer system includes the following major components, which are described in further detail elsewhere in this service information:

Body Control Module - The Body Control Module (BCM) (also known as the Signal Acquisition and Actuation Module/SAM) is located beneath the driver side end of the instrument panel in the passenger compartment, where it is secured to the fuse and relay block (also known as the SRB). Refer to DESCRIPTION .
Headlamp Washer Nozzle - A telescopic headlamp washer nozzle is located beneath each front lamp unit.
Headlamp Washer Pump/Motor - The electric headlamp washer pump/motor unit is located in a dedicated hole on the forward-facing side of the washer reservoir in the left front corner of the engine compartment.
Headlamp Washer Relay - The headlamp washer relay is an International Standards Organization (ISO) relay is located within the driver side front seat riser. It is concealed beneath the driver side front seat cushion on vehicles that are so equipped.
Multi-Function Switch - The multi-function switch is secured to and directly connected to the back of the clockspring/Steering Control Module (SCM) (also known as the steering column module/MRM) near the top of the steering column below the steering wheel and is completely concealed beneath the steering column shrouds. Only the switch control stalk and control knob extending from the left side of the steering column are visible, while the remainder of the switch is concealed beneath the steering column shrouds. The multi-function switch contains all of the switches for the front wiper and washer systems, as well as for the rear wiper and washer systems of vehicles that are so equipped. Refer to DESCRIPTION .
Steering Control Module - The clockspring/Steering Control Module (SCM) (also known as the steering column module/MRM) is secured near the top of the steering column below the steering wheel and is completely concealed beneath the steering column shrouds. Refer to DESCRIPTION .
Washer Reservoir - The washer reservoir is secured by screws to the left front inner fender shield and is located directly over the left frame rail in the left front corner of the engine compartment. A single reservoir is used with the unused mounting holes for the optional rear washer system washer pump/motor unit and the optional headlamp washer system washer pump/motor unit filled by black rubber plugs. The washer reservoir filler neck has a molded blue plastic cap and is accessed from the left front corner of the engine compartment.

Hard wired circuitry connects the headlamp washer system components to the electrical system of the vehicle. These hard wired circuits are integral to several wire harnesses, which are routed throughout the vehicle and retained by many different methods. These circuits may be connected to each other, to the vehicle electrical system and to the headlamp washer system components through the use of a combination of soldered splices, splice block connectors, and many different types of wire harness terminal connectors and insulators. Refer to SYSTEM WIRING DIAGRAMS . The wiring information includes wiring diagrams, proper wire and connector repair procedures, further details on wire harness routing and retention, as well as pin-out and location views for the various wire harness connectors, splices and grounds.
