Remove the center vents. Two screws go down into the center housing (remove)Open ashtray and remove the ash tray. remove the two screws that hold ashtray housing in place. once removed there are two screws going straight down into the lower center counsol,remove these. Now the complete housing can be gentely rotated out. The knob on the switch pulls off, sometimes it is stuborn. The wood trim then is removed. It has to be flexed in the center to remove. Very delicate work. Take your time, use good lighting and dont force it. Now you can see the screws that hold the switch in place. Your 1/2 way done.
Good Luck and have fun.
