What kind of link did you just post?

 

It's spam and I'm nuking him once this is posted. The airbag is wired through the yellow connector. The blue one, I'm not sure of its function, but it's more likely that the heating element is shot. If nothing else, buy another heated seat and transfer your upholstery onto it, or take it apart and install the heaters in your seat.
