How to Test the Chevy Headlight Switch

If you’re experiencing issues with your Chevy headlights, the first step is to test the headlight switch. To test the switch, you’ll need a multimeter. Here’s how to test the Chevy headlight switch:

  1. Disconnect the battery.
  2. Remove the headlight switch from the dash.
  3. Using the multimeter, check for continuity between each terminal and the switch’s body. There should be no continuity between any of the terminals and the switch’s body.
  4. With the multimeter set to volts, connect the negative lead to the switch’s body and the positive lead to the battery’s negative terminal.
  5. Check for voltage at each terminal with the switch in various positions. The voltage should match the wiring colors listed in the wiring diagram.

If the switch fails any of these tests, it needs to be replaced. If the switch passes all the tests, the issue may be with the wiring or the headlights’ bulbs.
