Turning the knob to high does nothing. Our trucks don't have a heater control valve.

Dan, if there is no heater valve, how is the flow of hot coolant stopped through the heater core, when using AC or cool air? Just curious.
There is a blend door in the plenum. It directs air over the heater core when you want heat. |
Dodgevity - There is one, but it's an on/off valve, not a more/less variable valve. And not all of the trucks have that, I understand!

It isn't stopped. Coolant always flows.
