glad you got the heating sorted, failure of the heated seat (usually driver side) is another common problem, my drivers seat hasn't worked since I bought the car.
Assuming the light is coming on when you press the switch it is almost certainly the element in the seat itself, the wires break over time due to the repetitive flexing caused literally by repeated bums hitting the seat.
there is a repair kit available and if you search on here you'll find a 'how to' guide on doing the fix but its something I personally don't want to attempt on mine as it involves taking the seat apart and using knives and glue, and more importantly getting it all back together again looking right.
Here's the info if you fancy a go.

Good grief, I think that is beyond me. I may check to see if someone can do it for me, failing that I will leave it also, thanks
