I had a go at stripping down a set of leather seats from a P reg Omega to see how difficult it was - my mini facelift T reg Omega seats are mint so I didn't want to practice on them. It is easy enough to get them apart, but when I got the cover off (easy enough apart from I couldn't work out how to get the black headrest bits in the very top of the seat out - ended up 'assisting' them with a hammer as I knew by that point I wouldn't be using the seat again - if anyone knows for future reference how to get these out whole I'd be interested to know in case I end up stripping my good seats....) I found that the heated seat pad in the back of the seat is securely fixed/sewn to the leather - not easy to separate if you were intending to replace the whole heating pad.
Unless I'm missing something, in which case I'd be very pleased to be educated as I'm not that practical....
I'm guessing that the easiest way is to either replace the seats in their entirety (I'm looking if someone has a set - please don't delete my post moderator, I'm working towards my 250 posts!!) or to repair the existing element, which is still hard to get to - you have to cut into the foam pad to find the two broken ends of element to join them back together again somehow. If anyone in Gatwick or Tonbridge area knows how to do this I'll gladly provide bacon sarnies, tea and some cash to get me some warmth for the winter.....
Thanks in advance.
