I tried last week. Didn't get too far. I used a couple of pairs of pliers to pull apart the hog ring clips underneath the seat, then folded the leather back. There are more hog rings in the crease of the seat. Easy to remove, but they won't be easy to put back on without the special pliars you can get for them.
Here's where I ran into problems:
The seatbelt is integral to the seat, it's not connected to the floor. That means likely taking the trim off the 'B' pillar to unbolt it, then dissassembling it all, which I'm not eager to do.
The airbag component on the side of the seat - I don't really want to fool around with it and I can't see how to easily remove it. The seat cover wraps around inside it, making it difficult to remove without taking the airbag apart.
All this is in an attempt to fix the heated seat, although I'm still not sure if it's the bottom of the seat or the back that's burnt out. From what i can see of the element it's still in good shape - although it would only take a little crack to stop it from working.
Anyone else have any ideas?
