Why is my heater fan not working in my Dodge Caliber?

Possible Reasons for Heater Fan Not Working in Dodge Caliber
There can be several reasons why the heater fan is not working in your Dodge Caliber. Here are some possible causes based on the search results:
1. Blown Fuse: A blown fuse can cause the heater fan to stop working. You can check the fuse for the radiator fan and make sure it hasn’t blown.
2. Faulty Blower Motor: A faulty blower motor can also be the reason for the heater fan not working. This can be caused by a bad electrical connector, broken wire, or a defect in the climate control unit.
3. Heater Blower Motor Resistor: The heater blower motor resistor controls the speed of the blower motor. If the resistor is faulty, it can cause the fan to stop working or only work at certain speeds.
4. Clogged Heater Core: A clogged heater core can restrict the flow of coolant and affect the heating performance in the vehicle.
5. Other Possible Causes: Other possible causes for the heater fan not working include a bad relay, control module malfunction, dirty evaporator, bad thermostat, faulty blend door actuator, bad water pump, or a dirty cabin air filter.
Troubleshooting Steps
To troubleshoot the issue with your Dodge Caliber’s heater fan, you can consider the following steps:
1. Check the fuse for the radiator fan and replace it if necessary.
2. Inspect the blower motor and its electrical connections for any signs of damage or loose connections.
3. Test the heater blower motor resistor to ensure it is functioning properly.
4. Check the heater core for any clogs or restrictions in the coolant flow.
5. If the above steps do not resolve the issue, it may be best to consult a professional mechanic or take your vehicle to a Dodge service center for further diagnosis and repair.
