Washer Pump Will Not Run

Turn ignition switch to "ON" position. Make sure washer solution is adequate, then push wash button and listen for relay to energize. With ignition still "ON" and wiring connected to wiper terminals, connect test lamp lead to ground and probe terminals 6 and 7.

• If lamp is off at both terminals, check for open in circuit to the pump.
• If lamp is on at one terminal, replace coil-park switch assembly.
• If lamp is on at both terminals, but one lamp is dim, ground the dim lamp terminal. If pump runs, check for open in wire between pump and dash switch or for a defective dash switch.
  NOTE: Delay wiper system is available as optional equipment. A separate control assembly is utilized which provides a variable delay of 1 to 20 seconds.
