- If not the specified value, replace the multifunction switch.
- With the WASH switch in the closed position, test for less than 2 Ω between the Accessory Voltage terminal 7 and the control terminal 6 (without N38) or terminal 8 (with N38).
- If greater than the specified range, replace the multifunction switch.
Washer Pump
- Ignition OFF, disconnect the harness connector at the washer pump.
- Install a 10 A fused jumper wire between the control terminal A and 12 V. Install a jumper wire between the ground terminal B and ground.
