Windshield Wiper/Washer Switch

Ignition OFF, disconnect the harness connector at the S82 Windshield Wiper/Washer Switch.
Test for infinite resistance between the signal terminal 1 and the low reference terminal 2 with the switch in the open position.
- If less than infinite resistance
  Replace the S82 Windshield Wiper/Washer Switch.
- If infinite resistance
Test for less than 2 Ω between the signal circuit terminal 1 and the low reference circuit terminal 2 with the switch in the closed position.
- If 2 Ω or greater
  Replace the S82 Windshield Wiper/Washer Switch.
- If less than 2 Ω
Test for infinite resistance between the signal terminal 3 and the low reference terminal 2 with the switch in the open position.
- If less than infinite resistance
  Replace the S82 Windshield Wiper/Washer Switch.
- If infinite resistance
Verify the resistance readings are within the specified range listed below between the signal circuit terminal 3 and the low reference circuit terminal 2 by pushing the switch in the listed positions below.
- Delay 1 : 3.75-3.85kΩ
- Delay 2 : 2.75-2.85kΩ
- Delay 3 : 1.95-2.05kΩ
- Delay 4 : 1.25-1.35kΩ
- Delay 5 : 765-775Ω
- If not within the specified range
  Replace the S82 Windshield Wiper/Washer Switch.
- If within the specified range
All OK
