When air conditioning or front defroster are turned on it will turn on A/C compressor which requires the A/C condensor to be cooled (via radiator fan).
I'm not a mechanic / technician but it sounds like your engine cooling thermostat is sticking open ( assuming that the electric engine cooling fans are not running continuously )
temperature sensor is bad
It is heated to such a high temperature by going over the engine which is really hot and is part of the cooling system, the cold air goes over some part of the engine and comes out hot. It is part of the cooling system of a car, so therefor if your car has overheating problems turn the heater on.
Either a cold plate, used with Peltier, or TEC (Thermo Electric Cooling) or a water block used with water cooling systems.
Yes a bad cold control will not let the compresser come on to check bypass cold control if compresser comes on replace cold control.
If the AC or Defroster is on, many vehicles will also turn on the cooling fan.
When ice comes in contact with skin, it absorbs heat from the skin to melt, resulting in a cooling sensation. The rapid heat transfer causes the surrounding tissue to cool quickly, triggering nerve receptors that detect changes in temperature, sending signals to the brain, which interprets this as a cold sensation.
Antifreeze is used in cars to prevent the engine's cooling system from freezing in cold temperatures and to raise the boiling point of the coolant to prevent overheating. It also helps prevent corrosion and rust in the cooling system components.
get your cooling system checked (eg: pressure test). it may be something wrong with your cooling (in my 97 Saturn if there's a cooling problem the check engine light comes on and the coolant temp defaults to the half line on startup)
AEM cold air intake, PACESETTER header, electric cooling fan swap, JET computer module
The electric auxiliary cooling fan may not be working.
The cooling fan generally does not run when the car is cold, but could be wired directly to the battery so that when the ignition is engaged, the fan comes on. This is not a factory modification but is often accomplished if the car tends to run hot.
