Heat maybe!
2006 C6 Coupe - Does anybody know if the inside heater on the corvette creates heat. I use the heater by turning off the compressor switch and turning the temperature up you would think you would have some warm are leaving the registers. I have raised the temperature as high as it will go and still no warm air. Maybe I'm using it wrong can anybody help?

HAH!! I wish someone can answer you cause I need that too, when the coolant temperature goes up to 100C compressor disconnected that's why u feel the warm air coming, well I'm not sure if there is a chance to solve it but what I'm sure about all the 06 models had that #$%

have you made sure that the system is set to output air through the registers you're feeling for air at? typically the car will output warm air through the footwell vents, which is practical because warm air rises. feel for the air here, or manually set the system to output to the console vents. Also, it's probably worth turning the fan control up to confirm.
I assume you're testing this while the car is warm and the engine is on, correct? Your coolant will have to be warm enough to heat up the heater core, and the coolant must be flowing for it to GET TO the heater core.
Just a side question: any particular reason why you turn off the compressor? gas mileage or compressor longevity could be potential reasons, I guess.
I've always left the A/C systems in my vehicles on auto. My father and most people his age I know like to adjust everything manually. Just an interesting side note.

If the engine coolant is at running temperature and you turn the heat on, you should have warm air blowing through the vents.
Check the hoses going into and out of the heater core, if they are hot then the problem does not lie within the coolant and heater core.
It's possible the temperature door is stuck or the HVAC module is not functioning correctly.

To answer your original question, no. The Heater does not make its own heat. It gets its heat from your engine cooling system. Your engine must be warmed up enough for you to feel any heat from the cockpit heater.

Thanks for trying to help. I'm aware of the engine needs to be up to temp in order to get the heater core working. Also aware of the floor vents or the upper register control. I can be driving for an hour and put the heater on but still no warm air. Difference between cold air and heated air is about 2 degrees. I have put the heater on to 90 degrees and no change in the air temp. Now here is the kicker one day I turned it on and it worked OK. Is there a thermostat driven switch that allows the coolant to flow through the core?

Normally I hate cars that have automatic cabin temp controls, but with the vette I just find that I set it to 71 and I rarely ever even touch the thing again. Early spring or summer. Now when the wife gets in that's a different story. Then its gotta be jacked up to 90. Mine's an 06, is there an issue with the heat on some?

If the outside temp is low enough AND the control is set to "Auto" then just adjusting the demand temp to 90° should allow heat thru whatever outlets are selected. If it's 80° outside then you probably won't get heated air thru any outlet since the inside of the car will already be at 90°.
Mine has been set on auto at 80° for years and the A/C comes on when the outside temp is as low as 65° on a sunny day.
There is no thermostat driven switch that allows coolant to flow thru the core.

What exactly you mean by "put the heater on to 90°"?
