Heated seats don't work anymore

So I haven't been able to use my heated seats for a loooong time. How much would it cost to get this fixed, and or can I do it. The wires in the seat have gone bad after getting in and out for 14 years. I am under the impression that I would need to remove the leather seat cover and replace it with a new one. Since the wires are in the cover/skin of the seat and its old.

Any thoughts?

How can I get this done at a lower cost and can I do it?


Both sides are not working.
