Common Ac Woes
Your Jeep Cherokee’s air conditioning system is vital. A broken AC is a major problem. You might face several common AC issues. These problems can make your drives uncomfortable. Let’s explore these typical woes.
No Airflow At All
Sometimes, no air comes out. The fan might not be working. This could mean a bad blower motor. The motor moves the air. A fuse might also be blown. Check your car’s fuse box. A relay could also be faulty. These parts control the fan speed.
Weak Airflow
Air might blow, but it’s weak. This is also frustrating. A clogged cabin air filter is common. This filter cleans the air. It can get blocked with debris. A dirty filter restricts airflow. The blower motor might be weak. It may not be powerful enough. The system’s ductwork could have leaks. Air escapes before reaching you.
Air Isn’t Cold Enough
The air blows, but it’s not cold. This is a frequent complaint. Low refrigerant is often the cause. Refrigerant is the cooling agent. It might have a leak. The AC compressor could be failing. This part pumps the refrigerant. The condenser might be blocked. Debris can stop airflow here. This prevents cooling.
Strange Smells
Does your AC smell bad? Musty odors are common. Mold and mildew can grow. This happens in damp areas. The evaporator core can harbor them. These smells enter your cabin. They make the air unpleasant. Address these smells quickly. They can affect your health.

Initial Checks
Your 2020 Jeep Cherokee AC isn’t blowing cold? Don’t sweat it. We start with easy fixes. These are initial checks you can do. They often solve the problem. Let’s dive in.
Cabin Air Filter
A dirty cabin air filter blocks airflow. This is a common cause. Your AC struggles to push air. Locate the filter. It’s usually behind the glove box. Remove the old filter. Inspect it for dirt. Replace it with a new one. This improves airflow significantly. Your AC might blow cold again.
Refrigerant Levels
Low refrigerant is a key issue. The AC system needs this gas. It cools the air. You might need a special kit. This kit checks the pressure. Follow the kit’s instructions carefully. If levels are low, recharge it. This can restore cooling. However, a leak might exist. A professional can find leaks.
Blown Fuses Or Relays
Electrical problems can stop cooling. Fuses protect the AC system. Relays control power flow. Check your owner’s manual. It shows fuse box locations. Find the AC system fuses. Look for blown ones. A blown fuse looks burnt. Replace it with a new fuse. Ensure it has the correct amperage. This might fix your AC.
Deeper Dive: Component Failures
Let’s go deeper. We examine specific part failures. Your 2020 Jeep Cherokee AC might not blow cold. Several components can fail. This section explains those failures. Understanding them helps diagnosis. It guides repair efforts.
Blower Motor Issues
The blower motor moves air. It pushes air through vents. A failing motor stops this. You hear no air sound. The fan may hum weakly. It might not spin at all. This stops cool air flow. Replace the blower motor. This restores airflow.
Condenser Problems
The condenser cools hot gas. It sits in front of the radiator. Debris can block airflow. Leaves and bugs are common. Bent fins also reduce cooling. A damaged condenser cannot work. It prevents cold air production. Clean the condenser fins. Repair or replace it if needed.
Evaporator Coil Concerns
The evaporator coil gets cold. It absorbs heat from cabin air. This coil can freeze up. Ice blocks airflow. You get little to no air. Moisture can also cause leaks. A dirty coil reduces cooling. Clean the evaporator coil. Fix any refrigerant leaks.
Blend Door Actuator Malfunctions
Blend doors control air temperature. They direct air flow. Actuators move these doors. A faulty actuator gets stuck. It may stay on hot air. Cool air cannot reach you. You hear clicking sounds. Replace the blend door actuator. This fixes temperature control.
Compressor Clutches
The compressor pumps refrigerant. Its clutch engages the compressor. A bad clutch prevents engagement. The compressor does not run. No refrigerant circulates. This means no cooling. Check the compressor clutch. Repair or replace it. Ensure proper engagement.
Refrigerant Leaks
Refrigerant is essential. It cools the air. Leaks mean low refrigerant. The system cannot cool effectively. You might smell a faint odor. Oily residue can appear. Find the leak location. Repair the leak promptly. Recharge the system. This restores cooling power.
Troubleshooting Steps
Your Jeep Cherokee AC is blowing warm air. This is frustrating, especially in hot weather. Don’t worry. We can troubleshoot this. Follow these steps. They will help find the problem.
Listen For The Compressor
Start your engine. Turn your AC to the coldest setting. Listen under the hood. You should hear a distinct click. This sound means the compressor is engaging. No click? The compressor may not be working. This is a common AC issue. It could be a bad clutch or fuse.
Check For Electrical Issues
Electrical problems can stop AC. Check your AC fuses. They are usually in the fuse box. The owner’s manual shows their location. Look for a blown fuse. Replace it with a new one. Also, check AC relays. A faulty relay can cause issues. Inspect wiring for damage. Loose connections cause problems too.
Inspect For Leaks
Refrigerant leaks stop cooling. Refrigerant is the AC’s coolant. Leaks reduce cooling power. Look for oily spots. These spots may show leaks. They often appear on hoses. Check AC components for damage. A professional can detect small leaks. They use special equipment.
Test The Blower Motor
The blower motor pushes air. It sends cold air into the cabin. If the motor fails, no air blows. Turn your fan speed up. Do you hear any fan noise? No fan noise means a bad motor. It might also be a bad resistor. This part controls fan speed. A broken resistor stops airflow. Or it causes slow airflow.
Diy Vs. Professional Repair
Your Jeep Cherokee’s AC is blowing warm air. This is frustrating. You face a choice. Fix it yourself? Or hire a pro? Let’s explore both options.
When To Tackle It Yourself
Simple AC issues are DIY-friendly. You might save money. Check for obvious problems first. Is the AC switch on? Are the vents open? Sometimes, the fix is easy. A clogged cabin air filter is common. Replacing it is straightforward. You can find tutorials online. Basic tools are often enough. A new filter costs little. This is a good starting point. Small issues don’t need a mechanic.
When To Call A Mechanic
Complex AC problems need expert help. Refrigerant leaks are serious. These require special equipment. Damaged AC components are tricky. The compressor might fail. The condenser could be bad. These parts are expensive. Replacing them takes skill. You need specialized knowledge. Messing up can cause more damage. This will cost more later. Safety is also important. AC systems use pressure. A professional knows how to handle this. They have the right tools. They can diagnose the exact problem. Trust a mechanic for tough jobs.
Preventative Maintenance
Preventative maintenance is your best defense. It keeps your Jeep Cherokee’s AC working well. Small checks prevent big problems. This saves you money and hassle. Your AC will thank you for it.
Regular Filter Changes
Your AC has a filter. This filter cleans the air. It stops dirt and dust. A clogged filter hurts airflow. It makes your AC work harder. Change your cabin air filter often. Check your owner’s manual. This is a simple, vital step. Clean air means a happy AC.
Ac System Checks
Schedule regular AC checks. A mechanic inspects the whole system. They look for leaks. They check refrigerant levels. They test the fan motor. These checks catch issues early. Early fixes are less costly. Keep your AC in top shape.
Avoiding Overuse
Don’t run your AC constantly. Use your windows sometimes. Fresh air is good. It lets the AC rest. Extreme use wears parts down. A little rest helps longevity. Your AC will last longer. Enjoy cool air when you need it.
