[s-cars] Heat issues

[Nick Stuart]

Hi all, doing a search through the archives I can't seem to find
anything relating to this. (seat heater issues seem to be a top the
list though :)  )

Anyways, I don't seem to be getting a decent amount of heat coming
through the vents, and if I just sit there idling there doesn't seem
to be any heat blowing through. Its still blowing air, just luke warm
air. Rev up to a couple of grand and hold it for a bit and the heat
comes back!  :(

Not sure what to fix or even look at here. All the vents seem to work
fine, everything switches as it should (when the stupid head unit
decides to have more then 2 buttons work).

Its getting to be cold out up here and would like to fix this soon.

p.s. The car always seens to warm up fine and have never had any
overheating issues besides with a stuck thermostat that got replaced,
as well as all the other heat related stuff behind the block.
