Your heater blows cold air. This is frustrating. The problem could be simple. A low coolant level is a cause. Coolant is essential for heat. The thermostat might be stuck open. This lets coolant flow too fast. The heater core could be blocked. Debris stops hot coolant flow. A faulty water pump also matters. It circulates coolant. A bad blend door actuator is possible. It controls air temperature.Lukewarm Air
The air is not hot. It is barely warm. This suggests a partial problem. Coolant might be low. Not enough coolant heats the air. The thermostat could be failing. It might not close fully. This allows too much coolant flow. The heater core might be partially blocked. Some hot coolant gets through. The radiator cap could be bad. It affects system pressure. This impacts heat transfer.Intermittent Heating
Your heater works sometimes. Then it stops working. This is very confusing. Air pockets in the cooling system cause this. They block coolant flow. The blend door actuator might be faulty. It moves erratically. This changes airflow randomly. A failing water pump can cause this. Its performance is inconsistent. The coolant level may fluctuate. This leads to intermittent heat.

Troubleshooting Steps
Your 2017 Jeep Cherokee heater is blowing cold air. This is frustrating. Don’t worry. We can fix this. Follow these troubleshooting steps. You can find the problem. You can get warm air again.
Check Coolant Level
Low coolant is a common cause. Your engine needs coolant. It also heats your cabin. Find the coolant reservoir. Check the level. It should be between the min and max lines. Add coolant if it is low. Use the correct type. Low coolant means no heat.
Inspect Heater Core
The heater core is like a small radiator. Hot coolant flows through it. Air blows over it. This heats your car. Look for leaks. Check the carpet. Is it wet and sticky? A leaking heater core needs repair. It might need replacement.
Examine Blend Door Actuator
This part controls air temperature. It moves a door. This door directs air. It can be hot or cold air. The actuator might be broken. Listen for clicking sounds. This often means a bad actuator. Replacing it restores temperature control.
Test Blower Motor
The blower motor pushes air. It pushes air through vents. Turn your fan speed up. Do you hear anything? No sound means a bad motor. A faulty motor means no air. No air means no heat. Test the motor’s wiring too.
Inspect Thermostat
Your thermostat controls engine temperature. It opens and closes. This regulates coolant flow. A stuck thermostat causes issues. It might stay closed. This prevents coolant from reaching the heater core. A failing thermostat needs replacement. This ensures proper engine heat.
Check Fuses And Relays
Electrical problems can stop heat. Fuses protect circuits. Relays switch power. Check your owner’s manual. Find the fuse box. Locate relevant fuses. Look for blown fuses. Replace them with new ones. Test the relays. A simple fuse can stop your heater.
Diy Repair Guide

You will need a drain pan. Disconnect the hoses from the core. Watch for any spills. The core is now loose. You can pull it out carefully.
Replacing The Blend Door Actuator
A blend door controls air temperature. An actuator moves this door. If it fails, heat stops. The actuator is often small. It attaches to the air box. Locate the faulty actuator. You might hear clicking noises. This signals a bad actuator. Unplug its electrical connector. Remove the mounting screws. Take out the old actuator. Install the new one. Secure it with screws. Plug in the electrical connector. Test the heating system. It should work now.
Flush The Heater Core
A clogged heater core blocks heat. Flushing clears out debris. You need a garden hose. You also need a bucket. Disconnect the heater hoses. Use a hose to flush. Send water through the core. Flush in both directions. See the dirty water flow out. Continue until water runs clear. This removes sediment. Reconnect the hoses securely. Refill the cooling system. Bleed air from the system. This ensures proper flow.
Replacing The Thermostat
The thermostat controls engine temperature. It also affects heater performance. A stuck thermostat causes cold air. Locate the thermostat housing. It is usually on the engine. You will need a wrench. Remove the housing bolts. Take off the old thermostat. Clean the housing surface. Install the new thermostat. Make sure it is facing right. Put the housing back on. Tighten the bolts evenly. Refill the coolant. Start the engine. Check for leaks. Your heater should now work.
