Or, you could avoid using any dropping resistors all together and wire the two in series
dropping 6v across each one. Of course you wouldn't have the choice of running each one
separately any more.
Since the truck has apparently been altered from it’s original design, i.e., converted to
12v, it shouldn’t make any difference to you if you use a single switch for the
heater/defroster.
