Nope, that fuse is a 20A in the SJB in the passenger-side footwell. Also, that circuit is not always hot, it loses power with the key, so pulling the fuse to restart it probably wouldn't have any effect. Those heaters are also just basic resistance heaters, they are likely shorted internally and need the element replaced.

So I scanned it and it says it has a code of B272C-20. Differential temperature fault driver side. Anyone else have that code?
