Component Testing

Windshield Wiper Switch

1. Ignition OFF, disconnect the harness connector at the S82 Windshield Wiper/Washer Switch.
2. Test for infinite resistance between the signal terminal 2 and the low reference terminal 1 with the high speed switch in the open position.
   • If less than infinite resistance 

     Replace the S82 Windshield Wiper/Washer Switch.

   • Go to next step: If infinite resistance 
3. Test for less than 2 Ω between the signal circuit terminal 2 and the low reference circuit terminal 1 with the high speed switch in the closed position.
   • If 2 Ω or greater 

     Replace the S82 Windshield Wiper/Washer Switch.

   • Go to next step: If less than 2 Ω 
4. Test for infinite resistance between the signal terminal 3 and the low reference terminal 1 with the low speed switch in the open position.
   • If less than infinite resistance 

     Replace the S82 Windshield Wiper/Washer Switch.

   • Go to next step: If infinite resistance 
5. Test for the resistance values listed below between the signal circuit terminal 3 and the low reference circuit terminal 1 by cycling the switch between Delay 1 and Delay 5.
   • Delay 1: 7.50-8.00kΩ
   • Delay 2: 1.29-1.34kΩ
   • Delay 3: 1.95-2.00kΩ
   • Delay 4: 2.78-2.82kΩ
   • Delay 5: 3.84-3.90kΩ
   • If not within the resistance values listed 

     Replace the S82 Windshield Wiper/Washer Switch.

   • Go to next step: If within the resistance values listed 
6. All OK
