Windshield Wiper/Washer Switch
- Ignition OFF, disconnect the harness connector at the windshield wiper/washer switch.
- With the wiper switch in the HIGH position, test for less than 2 ohms between the low reference terminal B and the signal terminal C.
- If greater than the specified range, replace the windshield wiper washer switch.
- While cycling the wiper switch through each delay and speed position, test for the specified resistance between the low reference terminal B and the signal terminal D.
IMPORTANT:
If the switch tests open in any switch position other than Off, test the signal circuits for a short to voltage before replacing the switch.
Wiper Switch Values
| Switch Position | Resistance |
|---|---|
| Off | Infinite |
| Mist | 300-364 Ω |
| Delay 1 | 3.48K-4.25K Ω |
| Delay 2 | 2.52K-3.08K Ω |
| Delay 3 | 1.78K-2.18K Ω |
| Delay 4 | 1.17K-1.44K Ω |
| Delay 5 | 697-851 Ω |
| Low | 300-364 Ω |
- If any switch position is not within the specified range, replace the windshield wiper washer switch.
