Why the air conditioning not cold when the car is stopped at a red traffic light?

Have you ever had the experience of your car's air conditioning not working properly and emitting just hot air, particularly when parked or stopped at a red light? What could be the source of this? AS AUTO will assist you in locating the answers.

The problem of the car air conditioner not cooling might be caused by a number of circumstances. One common occurrence is when the air conditioner works great while the car is moving but stops cooling instantly when the car comes to a complete stop. However, after a short period of motion, the cooling returns to normal. This symptom can be caused by a variety of factors, including:

   1. The front panel fan coil is turning slowly or has stopped - First and foremost, if you notice that the car's air conditioning is only cool when parked, check to see if the front panel fan coil is functioning properly. If the fan does not rotate or rotates at a slower rate than usual, heat will be dissipated when the automobile is still, resulting in the air conditioner not cooling adequately.

   2. Clogged Hot Coil Panel - The hot coil panel is critical for heat dissipation. A clog in the air vent or bent fins on the hot coil panel can hinder the air conditioner from cooling adequately. While the car is moving at high speeds, air pressure aids in continual heat dissipation, ensuring the air conditioner's normal operation. When the car is stationary, however, heat dissipation may be less efficient than it should be, resulting in insufficient cooling of the air conditioner.

   3. Damaged Air Conditioner Compressor - If the problem is not with the fan or the hot coil panel, it could be due to a faulty air conditioner compressor. If the compressor's piston wears out, the air conditioning liquid forced into the cold coil will have a low pressure level. This insufficient amount is insufficient to absorb the heat within the passenger compartment. As a result, when the engine is operating at high speeds, the air conditioner will only be cool and refreshing. However, it will not be as cool as it should be while using a light engine.

The air conditioner not cooling problem can occur for a variety of causes. It is initially stated that the problem occurs solely when the car is stationary. If you have problems with your air conditioning system, it is best to take your vehicle to a specialized garage that specializes in air conditioning systems. This will aid in more precisely solving the problem.
