The HVAC unit in the FRS/BRZ twins operate exactly the same way as Toyotas of past. The temperature of air blowing out the vents has to do with whatever temperature the HVAC is set to when off. Therefore, by turning on your fan controller and turning the temperature down to LO and then turning the fan off, you will get cool air blowing into the cabin rather than hot air.
So if you are experiencing hot air blowing into your cabin from the air vents when HVAC is off, perform the following:
1. Turn on the fan speed. This can be at any level, I prefer one notch.
2. Turn down the temperature. The lower the temperature, the cooler the air that blows out of your vents.
3. Turn off your HVAC system.
The temperature of the air coming out of your vents should now reflect what the HVAC controls were set to before you turned the system off.
Even when off, the HVAC is constantly blowing air into the cabin. That temperature of air is what you last set your settings to.
The works inversely as well. If you want warm air slightly blowing in on a cold day but don't want the fan working or HVAC system on, you can turn the system on briefly to set your desired temperature.
This is how the HVAC system works on all of our Toyotas with automatic climate control and now also the BRZ.
I hope this helps. Anybody correct me if I'm wrong.
