Step 1. Begin by removing the old switch installed on the door. Use a flathead screwdriver and carefully pry it out.
Step 2. After removing it, the baffle will become loose and you can separate the switch from it.
Step 3. After taking the switch out, disconnect it from the harness and remember its position.
Step 4. Install a new window switch and connect it to the wiring harness. Finally, reinstall the bezel bracket and wait for the tab to snap.
The above steps are only for reference, and we recommend you to ask the technician to do the replacement.
