How do I turn on the fog lights on my 2010 Chevy Silverado?
To turn on the fog lights, switch on the headlights and pull the headlight control knob outward to engage the fog lamps. If your truck isn’t equipped with factory fog lights, there won’t be a function to activate them.
This guide explains the standard control layout for a 2010 Silverado, what to do if the lights don’t come on, and how to troubleshoot common issues so you can restore improved visibility in foggy or poor weather conditions.
Where to Find the Fog Light Control
On most 2010 Silverado models, the fog light control is integrated into the left-hand headlight switch on the dash near the steering column. The knob supports Off, Parking Lights, and Headlights settings. Fog lights are turned on by pulling the knob outward when the headlights are in the On position. If your truck has an aftermarket setup or a different trim, there may be a separate fog light switch or a switch on the turn-signal stalk—consult the owner’s manual for the exact location.
Note for non-standard or aftermarket installations
Some vehicles without factory fog lights or with aftermarket wiring may not respond to the pull-out control. In those cases, look for a dedicated fog light button on the dash or a switch integrated into the steering column stalk, and refer to the specific installation documentation.
Steps to Activate Fog Lights
Follow these steps to activate fog lights on a typical 2010 Silverado equipped with factory fog lights.
- Start the engine or turn the ignition to RUN.
- Rotate the headlight switch knob to the Headlights ON position.
- Pull the headlight switch outward toward you to engage the fog lights. The fog light indicator on the instrument cluster should illuminate.
- To turn them off, push the switch back in toward the dash or rotate the knob away from the headlights position.
If your vehicle does not respond to the pull-out action, skip ahead to the troubleshooting section or check for a separate fog light control as described above.
Troubleshooting If They Don’t Turn On
If the fog lights won’t turn on after following the steps above, try these checks:
- Ensure the headlights are actually ON. Fog lights won’t operate if the main headlights aren’t active.
- Check the fog light fuse and relay in the vehicle’s fuse/relay box. Look for the circuit labeled for fog lights and replace a blown fuse or faulty relay as needed.
- Inspect the fog light bulbs themselves. If one or both bulbs are burned out, they won’t illuminate even if the switch is working.
- Test the fog light switch for proper operation. A switch that feels loose, sticks, or doesn’t click may be faulty and require replacement.
- If the truck has been modified or the fog lights were added aftermarket, verify wiring integrity and ensure power is actually reaching the lights.
If problems persist after these checks, you may need a professional diagnosis to verify wiring, relays, and ballast (if applicable) or to confirm compatibility with your vehicle’s electrical system.
Summary
In a 2010 Chevy Silverado, turn on the headlights and pull the left-hand headlight switch outward to activate the fog lights. If they don’t illuminate, verify the fuse/relay, bulbs, and switch, and check for any dash-aided or stalk-mounted controls that might differ by trim or aftermarket installations. When functioning correctly, the fog lights should provide improved low-visibility illumination and help you see the road edge more clearly in foggy conditions.
