What Are the Solutions for Car Air Conditioning Not Cooling?
2 Answers
Methods to address car air conditioning not cooling: 1. Fuse: If the fuse is blown, replace it; 2. Circuit wires: If the circuit wires are detached or broken, repair them; 3. Air conditioner: If there is a fault in the air conditioning system, repair or replace the air conditioner; 4. Compressor belt: If the compressor belt is loose, slipping, or damaged, adjust its tension or replace the belt; 5. Exhaust valve: If the compressor's suction and exhaust valves are not functioning properly, repair or replace the exhaust valve; 6. Electromagnetic clutch: If the electromagnetic clutch is not engaging well, repair or replace it; 7. Expansion valve: If the expansion valve is opened too wide, preventing the refrigerant from evaporating in time in the evaporator, clean, repair, or replace the expansion valve. When adjusting the expansion valve, observe the low-pressure pressure while making adjustments.
When I find that the car air conditioning is not cooling, it's often due to insufficient refrigerant or a leak, so it's necessary to start with the basics. First, check if the air filter is dirty or clogged, as a blockage can affect ventilation and requires replacement or cleaning. Next, inspect whether the fan is working; if it doesn't turn on after starting the air conditioning, it might be an electrical issue or malfunction. Then, check if the compressor is operating normally—unusual noises upon startup could indicate a failure, requiring professional repair. If the refrigerant R134a is low, it needs to be topped up, but avoid adding too much yourself to prevent excessive system pressure that could damage components. Parking in the shade to reduce the air conditioning load can extend its lifespan. Finally, if these simple checks don't help, it's best to visit a professional shop for a comprehensive leak or electronic component inspection. Remember, timely action prevents driving in extreme heat during summer, which could affect safety.
