Goldwing,

Discount tire will rebuild the TPMS sensors in the rims. However, they do
charge for the service. At least, the shop here in Georgia did.

I agree, it is a stretch that the module responsible for controlling boost
would double as the controlling module for the heated seats. But, I've
seen stranger things. I think I'd take that car back to the shop and ask
for a real technician.
