Simply "pops" into the wood trim.

Most of the time you wouldn't need to wood trim at all.

Hardest part is getting the console wood out to replace the switch.

Process is long and detailed. Plenty of opportunity for damage to existing items.

Suggest you purchase an AllDataDIY subscription for about $20. There are detailed instructions on how to get the console wood out so you can change the switch.

All Parts Express (top of page Buy Parts "Pull Down" menu) has your switch
6 bucks cheaper.

I replaced mine (W124) years ago when the knob broke off the shaft. Don't remember the process being all that difficult.

As said, removal of the console is necessary, but I had been in there before.

As I indicated before, loosen the screw on the ashtray lid after removing the ash tray insert, slide it upward and remove. Then locate the two lateral (sideways) torx that hold the upper and lower panels together and remove them. Once they are removed and the shift trim is removed by pulling up on it, the panel can be raised on the ash tray side, and then pulled slightly forward to release the catch on the arm rest side. The two phillips screws that you see looking straight down hold the upper console panel.
