There is a tab on the underside of the switch, pull it out like you are turning on the fogs. Push it in with a small tipped tool and the” knob” will Pop off....its dead center underneath the knob...
Next.....and this you need to be careful with...
Use a long t20 and remove thetorx bit in the recess of the switch...you'll see a large thin nut around the switch center post, remove it...
This will let you remove the larger black plastic surround of the switch, there is a ribbon cable on it, so remove very carefully....
