What are the reasons for the Jeep Compass air conditioning not cooling?

Possible causes for the Jeep Compass air conditioning not cooling include: 1. Insufficient Freon: The Freon level is too low. 2. Compressor issues: Problems with the compressor or expansion valve, leading to abnormal pressure in the air conditioning system. 3. Air conditioning heat dissipation system issues: Problems with the heat dissipation system, severe blockage of the condenser and radiator, resulting in poor heat dissipation and excessively high temperatures, causing the air conditioning to not cool properly. Relevant information is as follows: The Compass air conditioning cooling is controlled by the AC switch on the air conditioning control panel. When the air conditioning is turned on, the AC switch is activated, the compressor electromagnetic clutch engages, and the compressor starts working. The compressor compresses the refrigerant, turning it into a high-temperature, high-pressure gas, which then dissipates heat to the air at the condenser in front of the vehicle, condensing into a high-pressure liquid. After passing through the receiver-drier and being filtered and dried, it reaches the expansion valve, where it is throttled and depressurized into a low-pressure liquid, finally reaching the evaporator inside the vehicle cabin. The refrigerant evaporates and absorbs heat in the evaporator, thereby achieving cooling. For heating, the AC switch is turned off, and hot water from the engine radiator flows to the heater core in the blower unit. The blower forces air over the heater core, producing warm air for heating.
I've also experienced air conditioning cooling issues with my Jeep Compass, which could stem from several causes. Refrigerant leakage is the most common reason; the Freon in the AC system slowly leaks out, and the cooling effect disappears. Next is AC compressor failure—it's like the heart of the engine; if it stops working, cold air won't come out. A clogged condenser or a non-functioning fan can also lead to insufficient cooling. Another possibility is a blocked expansion valve or electrical wiring issues, such as a blown fuse. Regular inspections are essential. Driving in summer with a malfunctioning AC is really annoying, affecting comfort and even posing risks. It's best to get it checked and repaired at a professional shop promptly—don't delay. Experience tells me that addressing these minor issues early can save big money.
When I was repairing my car, I found that if the Jeep Compass air conditioning is not cooling, you can start with some simple checks. Turn on the AC and see if the fan is running—if not, the fuse might be blown. Check if the cabin air filter is dirty, as a clogged filter can restrict airflow. Also, verify if the temperature settings are correct or if the wrong mode is selected. If all these seem normal, it could be due to insufficient refrigerant or a system leak. It’s recommended to try replacing the filter first. If that doesn’t help, use tools to check the pressure or seek professional diagnosis at a shop. A broken AC makes driving uncomfortable in hot weather and may even damage other components. Don’t delay repairs to avoid turning a small issue into a major problem. Safety first.
I believe the common issue of Jeep Compass AC not cooling often lies in the compressor. Once it fails, the entire system shuts down. The compressor starts via an electromagnetic clutch—if the contacts wear out or the belt loosens, it can't compress the refrigerant, and cold air naturally won't come out. Driving long hours in high temperatures can easily cause the compressor to overheat and fail. When you notice the AC isn't cooling, listen for a humming sound from the compressor to diagnose the problem. Prompt replacement or repair avoids costlier engine damage and ensures peace of mind while driving.
