Cleaning the right side switch. I heated up the back of the switch assembly first with a heat gun to carefully soften the plastic. Then I used my pocket knife blade to , on the front side of the switch, to pry each of the sides off of the little rocker teeth. I suggest warming the assembly if it is cold outside as cold plastic snaps off and warmer plastic will flex. Note the little silver “ninja stars” over each switch. They will fall out so do this over a table so you don’t lose anything.
