It sounds like you're experiencing an issue with your 2009 Chevrolet Aveo's air conditioning system blowing hot air. While there could be various causes for this problem, here are some steps you can take to troubleshoot before taking your car to the dealer:
Check Air Blend Door: The air blend door controls the mix of hot and cold air coming from your vents. If it's stuck in the wrong position, you might get only hot air. Check to see if the temperature control knob/slider is working as it should.
Inspect Cabin Air Filter: Some vehicles have a cabin air filter that can become clogged over time. A dirty or blocked cabin air filter might restrict airflow and impact the effectiveness of the A/C system. Check your vehicle's manual to locate and inspect the cabin air filter.
Clean Condenser and Evaporator Coils: If the condenser or evaporator coils are dirty or clogged, it can affect the efficiency of your A/C system. These coils are typically located in the front of the vehicle. While cleaning them might help, it's usually best to have this done by a professional to avoid damaging delicate components.
Check for Refrigerant Overcharge: While your system reading at 60 psi might indicate overcharging, it's important to note that the proper refrigerant levels can vary based on factors such as ambient temperature. Adding or removing refrigerant without proper knowledge can potentially damage your A/C system.
Inspect A/C Clutch: You mentioned that the compressor clicks on, but make sure the A/C clutch is engaging properly. If the clutch isn't engaging, it could result in hot air blowing.
Check Cooling Fans: Cooling fans help dissipate heat from the A/C system. Make sure the cooling fans are working as they should, especially when the A/C is turned on.
