It could be a pulley that is seized up on the a/c drive belt that's most likely the problem
sounds like the thermostat is sticking
THE CAUSE for this is that when your cold air is on the petrol is used to create air. and that is how cars create cold air
The air temperature of the air is cold when it rains and the cloud temperature is cold when it rains
Sounds like it is low on coolant.
TEMPERATURE Cold air is denser
One cause of a cars air conditioning to brake is the temperature of the air conditioner. Using to much cold air at a certain amount of time can damage your air conditioner.
Air pressure is the weight of the atmosphere pressing down on the earth. Temperature raises and lowers the pressure by changing density of said air. For example check the air in your cars tires cold, then hot-with no other change besides temperature, you will get different readings-this is normal and the reason you are supposed to adjust when cold.
The average aircraft will have temperature gauges for the following: Outside air temperature, Engine air inlet temperature, Engine exhaust temperature, cabin temperature, and that's just on a small aircraft. So which temperature gauge do you mean?
If the fan is moving and blowing cold air, your cold air intake is working properly. So long as your car isn't overheating it's a safe bet that the intake is functioning properly. Quite simply your temperature gauge will head straight for the red if the engine isn't getting cold air.
Low coolant, check when engine is cold.
It is easier and cheaper to replace the temperature sensor--try that first
Can be a defective temperature sending unit. If you just chance the coolant can be air trapped in the cooling system. You would need to bleed all air from the system. Can also be a defective gauge, but highly unlikely.
