89GTA TPI Does AC Air go through Heater core?
Assuming I were to remove the Heater control valve and the heater core had heat all the time.. If I were to switch on the AC, or just vent air.. would it be hot/hotter? IE would the air go through the heater core? I assume not but I'm doing an LT1 Swap and I'm at the stage of running new heater hoses.. WOuld like to dress up and simplify things.

what about when you have the a\c on, but temp selector on heat? does it go through the heater core first? or does it seperate and go through each individualy?

it then goes through the Evap(A/C) then through the heater core(air always goes through the Evap(A/C))

do you know how to add a heater coolant shutoff valve? my a/c doesn't work and the heat just pours out of the heater core. i heard the fix is to install this valve....but how to do it?
