I have an 82 mc9, and am taking out the over the road ac so as to be able to use the compartment. I have found one valve to shut down flow to the bus heater. The question is, is the other valve the electric one in the front bay, or should i be looking for another manual valve? any and all help is greatly appreciated, so thanks in advance.also anyone in SoCAl need any of the parts? the over the road ac works perfectly.

2 manual valves in the engine compartment. 1 is inside the passenger side engine compartment door in the line near the starter. The other one is up behind the gear mounted alternator (almost above the transmission and slightly off center on the drivers side. The electic valve in the front baggage compartment is a "Gradustat" and controled the amount of water that flows through the heater core to regulate air temperature in the AC/Heater system. Hope this helps, Jack
