Will this switch work with my aftermarket fog lights?

This switch controls the factory fog light wiring circuit. If your aftermarket lights are wired to the OEM harness, it works fine. If they're on an independent relay circuit, you'll need to verify compatibility with your installation setup.

Do I need to remove the dash cluster to install this?

No. The switch mounts from behind the dash panel into the factory cavity. You'll access it from underneath or behind the steering column depending on your comfort level—most installs take under 30 minutes with basic hand tools.

What if the switch doesn't turn on my fog lights after installation?

First confirm the bulbs and fuses are good. Then check that your fog light relay and wiring are intact. If the switch clicks but lights don't respond, the issue is likely upstream in the circuit, not the switch itself. Refer to your owner's manual wiring diagram for circuit testing.
