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 high speed switch in the open position.
- If less than infinite resistance
Replace the S82 Windshield Wiper/Washer Switch.
- If infinite resistance
- If less than infinite resistance
- Test for less than 2 Ω between the signal circuit terminal 1 and the low reference circuit terminal 2 with the high speed switch in the closed position.
- If 2 Ω or greater
Replace the S82 Windshield Wiper/Washer Switch.
- If less than 2 Ω
- If 2 Ω or greater
- Test for infinite resistance between the signal terminal 3 and the low reference terminal 2 with the low speed switch in the open position.
- If less than infinite resistance
Replace the S82 Windshield Wiper/Washer Switch.
- If infinite resistance
- If less than infinite resistance
- Test for the resistance values listed below between the signal circuit terminal 3 and the low reference circuit terminal 2 by cycling the switch between Delay 1 and Delay 5.
- Delay 1 : 3.8kΩ
- Delay 2 : 2.8kΩ
- Delay 3 : 1.9kΩ
- Delay 4 : 2.8kΩ
- Delay 5 : 770Ω
- If not within the resistance values listed
Replace the S82 Windshield Wiper/Washer Switch.
- If within the resistance values listed
- All OK
Relay Test
- Ignition OFF, disconnect the appropriate relay.
- Test for 60-200 Ω between terminals 85 and 86.
- If less than 60 or greater than 200
Replace the relay.
- If between 60-200 Ω
- If less than 60 or greater than 200
- Test for infinite resistance between the terminals listed below:
- 30 and 86
- 30 and 87
- 30 and 85
- 85 and 87
- If less than infinite resistance
Replace the relay.
- If infinite resistance
- Test for less than 5 Ω between terminals 30 and 87A.
- If 5 Ω or greater
Replace the relay.
- If less than 5 Ω
- If 5 Ω or greater
- Install a 10 A fused jumper wire between relay terminal 85 and 12 V. Install a jumper wire between relay terminal 86 and ground.
- Test for less than 5 Ω between terminals 30 and 87.
- If 5 Ω or greater
Replace the relay.
- If less than 5 Ω
- If 5 Ω or greater
- All OK
