That's a good thought about the valve, and a fairly easy fix, but the A/C system's valve should do that. A small ball valve will be in order I think. I worked for Peterbilt in Calgary for a long time also, I guess we have another thing in common. I remember lots of the trucks with a couple of ball valves to cut off the hot coolant to the heater and bunk. Turned a few on too when it got cold outside and the driver came in with a complaint of no heat. It disappoints me that I have to do that, but it will make a big difference and less load on the A/C system. Good advice.
