Multifunction Switch - Static Test
WARNING: This page is about a different car, the 2011 Chevrolet Volt. However, it is still accessible from the selected car via links, so may be relevant.
- Disconnect the X1 harness connector at the S82 Windshield Wiper/Washer Switch.
- With the S82 Windshield Wiper/Washer Switch in the HIGH position, test for less than 5 Ω between the terminal 2 and the signal terminal 1.
- If greater than the specified value, replace the S82 Windshield Wiper/Washer Switch.
- While cycling the S82 Windshield Wiper/Washer Switch through each delay and speed position, test for the specified resistance between the low reference terminal 2 and the signal terminal 3.
NOTE:
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.
