OK seems that some have a heater control valve some don’t I have a 93X. From what I found it should be located near the firewall as the hoses enter the heater core. As you can see from the photo there is nothing it is a straight hose from the core to the block and pump.
Now the reason for concern, I just rebuilt and converted the A.C. to R134 replaced everything but evaporator and condenser. The air blows kind of cold just a little better than it did. With the control on Max A/C and the fan on high (#4 position) it blows kind of cold BUT as I drop down to #3 fan speed it blows a good 10 deg. colder even more as I drop the fan down to low (1) and 2.
Now my thought if there is no heater control valve my thinking tell me the heater core is flowing with hot water and hindering the A/C.
I am thinking of putting a manual shut off valve on the heater hose to bypass the heater core. I am in Florida after all and don’t use heat much. It wouldn’t be that bad to open and close a valve say in the Fall & Spring.
How about some of you guys chime in with ideas, thoughts and/or suggestions.
Thanks
