Anyhooo. Here's the quick summary of what I did - it took a little over an hour to remove and replace everything.
- Removed foam seal around the door for access - easily pulls off and pushes back into place.
- Removed plastic trim that keeps carpet in place around floor and door for access to screws - pull gently to avoid breaking plastic tabs.
- Removed the rear bench seat (see attached doc "install rear seat cushion.pdf").
- Removed the side bolster (see attached doc "install seat side bolster for backrest in rear.pdf").
- Replaced switch block - gently remove electrical connector from plastic harness.
Good luck!

I have a couple of tips:
1. the rear seat bottom is easy to remove -- just pull up on it on both sides.
2. I unbolted the outboard seatbelt bolt (a torx bolt) after removing the side bolster, but I'm not sure this was necessary.
3. Folding down the seat-back on the side you're working on makes it easier.
4. I would also remove the cargo cover to make things easier.
5. I found the hardest part to be removal of the old switch. I removed the electrical connector from the old switch, then removed the whole panel that it snapped into. To remove the plastic panel, you have to first remove the plastic threshold that covers the floor carpeting. It is held in place by a 10mm hex nut and I think three metal clips that the plastic threshold tabs go into. Then you have to unbolt (10mm hex nut) the upper plastic piece that the switch is inserted into. This also has tabs that snap into metal clips. You can then remove the whole plastic piece. I used a plastic pry bar to widen the slot that the switch snapped into and the switch came right out. I don't think I could have removed the switch from the plastic panel without removing the panel from the car. The new switch snapped right into the plastic panel from the backside.
6. Next connect the white electrical connector to the switch and reinstall the top plastic panel and then the plastic threshold that covers the floor carpeting.

and on top of that - any ideas on the steps to replace the switch?
