Yes its the heater, from what I can tell the valve is working, because I can
kinda hear it change, if that makes since.

Hi Tom,
You said it's your heater that isn't heating the cab....correct?
Your engine cooling system might be fine. You could have a stuck Heater
Control Valve or the Fresh Air Damper could be stuck open. Just something
else to think about.....
