Step-by-Step Replacement Process

1. Prepare Your Vehicle

Park your car on a flat surface and turn off the engine. Engage the parking brake for safety. Gather all tools and the replacement switch before starting.

Reassemble and Final Checks

Once confirmed that the switch works properly, carefully snap the dashboard panel back into place. Double-check that all clips and screws are secure. Start your vehicle again and verify the AC controls operate smoothly.
