Troubleshooting Air Conditioning Issues: From Refrigerant Leaks to Blower Problems

Stay Cool with Auto Leaders by Your Side

There’s nothing quite like hopping into your car on a hot summer’s day, cranking up the A/C… and being greeted with nothing but warm air. Your vehicle’s air conditioning system is essential for comfort, especially during Australia’s scorching summers, but like any system, it can run into trouble. From refrigerant leaks to blower motor problems, there are several culprits that could be behind your Air Conditioning woes—and Auto Leaders is here to help you sort them out.

Common Air Conditioning Issues and How to Spot Them

1. Weak or No Airflow

If your vents are barely blowing air—or not blowing at all—it could be due to:

  • A failing blower motor
  • A blocked cabin air filter
  • A faulty A/C control module
  • Damaged fan relays or resistors

You might notice that the airflow starts strong and weakens over time, or that it only works at certain fan speeds. A quick filter replacement can sometimes solve this, but if that doesn’t help, it’s best to have the blower motor checked by a professional.

2. Air Isn’t Cold Enough

When your Air Conditioning isn’t cooling the cabin like it used to, the issue is often a refrigerant leak. Over time, tiny holes in hoses or seals can let refrigerant escape. You might also be dealing with:

  • A malfunctioning compressor
  • A clogged expansion valve
  • A damaged condenser

These issues require proper diagnosis using specialised equipment, so don’t risk DIY repairs. Auto Leaders technicians use industry-grade tools to locate leaks and safely recharge your A/C system.

3. Bad Smells from Vents

Funky odours wafting through the vents often point to mould or mildew in the evaporator coil. This can happen when moisture builds up in the system—usually due to poor drainage or lack of use. Sometimes, it’s just a dirty cabin filter. Either way, your car might need an A/C sanitisation or evaporator clean-out to eliminate the smell and prevent respiratory issues.

4. Strange Noises When A/C Is On

Clicking, rattling, or squealing sounds when your A/C is running could indicate:

  • Debris in the blower motor
  • A worn-out compressor clutch
  • A damaged fan belt

Any unusual noise warrants inspection, as ignoring it could lead to more expensive damage later on.

Why You Shouldn’t Ignore A/C Problems

Even if you can “live with it,” a failing A/C system can lead to other issues down the track. For instance, a leak in the system allows moisture in, which can corrode components or damage the compressor. Plus, it impacts overall comfort and can even affect your car’s resale value.
