There’s nothing worse than a failing air conditioner on a hot Australian day. Whether it’s blowing warm air, making strange noises, or not working at all, your car’s air conditioning system needs attention to keep you cool and comfortable. At Repco Authorised Service, we understand the importance of staying cool, so here’s a guide to help you identify and address common car air conditioning problems.
If your air conditioner blows warm or hot air, it may indicate a refrigerant leak or compressor failure.
Restricted airflow could result from a clogged cabin air filter, a failing blower motor, or a blocked evaporator.
Clicking, hissing, or grinding sounds often point to issues with the compressor or a loose belt.
Musty smells can result from mould or bacteria growing in the system.
Visible fluid near your car’s front could be refrigerant or another component leaking.
Before heading to the workshop, you can try these basic checks to diagnose the problem:
A clogged cabin air filter can reduce airflow and spread dust and allergens.
If the air is weak or not blowing at all, the blower motor may be faulty.
What to Do: Turn on the fan at various speeds. If there’s no response, the blower motor or its resistor might need replacement and you will need to book a service appointment.
Leaking refrigerant often leaves an oily residue on components like hoses or the compressor. If you find anything suspicious you will need to book a service appointment.
While some basic troubleshooting is safe to do yourself, air conditioning systems require specialised tools and knowledge.
