the a/c heater components are currently removed from my camaro, to include all the a/c components and the engine runs with a a/c delete pulley. that's fine but i want heater,defrost, vent system to work. the wiring harness for the blower motor is there, plus a a/c heater control panel installed in the dash area. i don't know if the panel is good. i see that thirdgen ranch has the blower motor/ac fiberglass housing for sale to include the motor. my question is, can i install this in the firewall area and connect the wires to the blower, and then will the air circulate to the vents in the window for defrost and will the heater work. i think air will leak out when the freon tubes were installed.
