It's a real pain to remove. You have to unscrew the dash bezel & pull it away from the dash to gain access to the switch.
If the shaft is still attached to the switch you need reach up inside the dash & push a button in to release the shaft before the bezel can be pulled away from the dash.
This isn't too hard if your a contorsionist with small arms.
Or you could yank the shaft from the switch since your replacing it anyway. This will probably destroy the switch.
