When I turn the heat on in my 2017 Toyota Camry, is there an actual heater core that is working or is it just channeling more engine heat to the cabin?
If there is a heater core or similar component involved, when I have my fan setting to 0 and the heat setting to max, is that exercising the heater core component with no benefit or is the car logic smart enough to not run the heater core when the fan setting is zero.
Similar question for A/C with the fan setting to zero and temperature setting to max A/C is this exercising the A/C to no benefit?
Where should i keep the temperature setting when no fan is engaged?
Does it matter if I'm on inside or outside air?
Realize in that particular design the hot water always flowing through the heater core and the only reason you get hot we're not at is because the blend door either opens to let air go through heater car or the door is closed and no air blows for the heater core so you don't get heat. And an AC system basically works the same way. Either air is blowing over the AC evaporator that makes it cold or it isn't depending where the blend doors are. Once you run either system it doesn't really matter what speed you have them on. They're working. The AC compressor only has one speed itself
Thank you Scotty. Does this mean the heater core has hot water going through it regardless of the heat setting? I just wanted to know if I'm running the heater core without benefitting from it and I want it to last as long as possible.
I assume the A/C system is not running unless the light above my A/C button is on, correct?
