How is it that I am able to construct an entire Truck out of bits and parts, but I can't figure out how to add a fan and a tube to the dashboard from the engine compartment as a heater ?

AC I can see as not fitting the game (but it too would be nice) but something as simple as jumping in my truck when I am "Freezing" should at least have the same effect as holding a burning branch.

Also, being on my motorcycle and cruising at top speed and being "Sweltering" ?

Please consider looking at this.
