I have struggled to find any information on how to remove the seat button and switch. The switch itself cannot be removed without removing the plastic trim around the outer side of the seat base. The seat will need to be removed for this. Once removed undo the few screws that hold the plastic in place, once loose unhook the two seat reclining cables they should just slide out there housings. Once you have the assembly off the seat it should look like this: (Two Small clips on each side to release the switch)
Once removed you will need to slide the metal plate across with the use of a small flat blade:
The plate should lift out showing the back of the switch:
The next step will need a steady hand, its this white plastic component that breaks. It's attached to the black switch with one clip either side, using a small flat blade to lift them:
Wiggle the black button while gently prizing the clips open. Once off you should be left with the following components:
Enjoy
