CAR AC FUSES KEEP BLOWING 12 WAYS TO FIX

If your car air conditioner fuses keep blowing here are 12 possible reasons and repairs. This video is about how sometimes you can diagnose and repair a car air conditioner that is not working without using any complicated electronic diagnostic tools or experience.
Fuses Blowing Immediately Upon Turning On the Air Conditioning
Check for Visible Wiring Issues:
Inspect the wiring around the air conditioning components for visible damage, such as frayed wires, exposed metal, or loose connections. Pay close attention to areas where wires pass through the firewall or around sharp edges.
Inspect the Fuse Box:
Check the fuse box for any signs of corrosion, damage, or loose connections. Ensure the fuses are seated properly and that there are no melted or damaged fuse slots.
Test the AC Relay:
Swap the air conditioning relay with another relay of the same type in the fuse box to see if the problem persists. If the fuse stops blowing, the relay might be faulty.
Examine the Compressor Clutch:
With the engine off, visually inspect the compressor clutch for signs of damage or wear. A damaged or misaligned clutch might draw excessive current when engaged.
Fuses Blowing After Operating for a While
Check the Cabin Air Filter:
Locate and inspect the cabin air filter. If it’s dirty or clogged, replace it. A clogged filter can cause the blower motor to overwork and draw more current.
Clean the Condenser and Radiator:
Inspect the front of the car for debris blocking the condenser or radiator. Clean any leaves, dirt, or other obstructions that could impede airflow and cause the system to work harder.
Monitor the Airflow:
Ensure all vents inside the car are open and unobstructed. Blocked vents can cause the blower motor to work harder, increasing the electrical load.
Inspect the Blower Motor:
Listen for unusual noises from the blower motor when the air conditioning is running. Squealing or grinding noises might indicate a failing motor drawing too much current.
Feel for Heat Buildup:
After the air conditioning has been running for a while, feel the wiring and components for excessive heat. Overheating wires or components can indicate increased resistance or overworking parts.
General Tips for Both Scenarios
Replace the Fuse with the Correct Rating:
Always replace blown fuses with ones of the same amperage rating. Using a higher-rated fuse can cause damage to the system.
Avoid Overloading the Electrical System:
Ensure that no additional high-current accessories are connected to the same circuit as the air conditioning system. Disconnect any aftermarket accessories to see if the problem persists.
Check the Battery and Alternator:
Ensure the car’s battery terminals are clean and secure. A weak battery or faulty alternator can cause electrical issues. While you may need a multimeter to check these properly, you can still visually inspect the connections for corrosion or looseness.
