1. Low Refrigerant Level: Check if there's enough refrigerant in your vehicle's AC system. Low refrigerant can cause the AC blower to stop working.
2. Faulty AC Compressor: If the AC compressor is faulty, it can cause the blower motor to stop as well.
3. Defective Blower Motor: If the blower motor is defective, it won't be able to circulate the cool air from the evaporator core, leading to the blower stopping.
4. Blocked Air Vents: Clogged or obstructed air vents can restrict airflow, putting a strain on the blower motor and potentially leading to its failure.
5. Electrical Issues: Faulty wiring, loose connections, or a blown fuse/relay related to the AC blower motor circuit can also cause the blower to stop working.
Troubleshooting:
1. Refrigerant Level: Consult your vehicle's owner's manual for the recommended refrigerant levels. If necessary, get the refrigerant recharged or topped up by a qualified AC technician.
2. AC Compressor: Listen for any unusual noises when turning on the AC. A faulty compressor might produce a clicking, grinding, or chattering sound. Consult a professional for repair or replacement.
3. Blower Motor: Inspect the blower motor visually and check for any damage or signs of overheating. If the blower motor is defective, it might need replacement.
4. Air Vents: Clean the air vents and make sure they are clear of debris or blockages.
5. Electrical Issues: Check the electrical connections and wiring related to the blower motor. Replace any blown fuses or relays. If the problem persists, seek assistance from an auto electrician or mechanic.
Remember that electrical and AC system work should only be performed by trained individuals for safety reasons. If you're unsure about handling any of the above checks or repairs, it's best to seek professional assistance.
