The metal lines to the mid body heating unit are rusty and leaking. I would like to replace the 6 outlet heater control valve with a four (and keep the rear heater working) or a two and just use the front heater. Can this be done and where is the heater valve hiding?

What makes you think you even have a heater valve?

You likely do not.

I have no idea what that part number is but your truck did not come with a valve like that, at least not in the US.
