So a GOOGLE on "final stage" or "final stage resistor" - or just go to
the dealer and get one. Takes about 15 minutes to install. It's located
behind the carpeted panel on the right side of the console/tunnel.

Very common problem... the new one has been "improved" and hopefully
won't fail as often.
