What is an air vents not working assessment?

This assessment is carried out when no air is coming out of your cabin vents, even though the blower fan and AC system should be running. The issue may be caused by a faulty blower motor, blocked cabin filter, broken vent controls, or problems with the ventilation system. An assessment identifies the exact cause before repairs are carried out.

Why do you need this assessment?

If no air is coming through your vents, you lose heating, cooling, and window demisting inside your vehicle. This not only makes driving uncomfortable but can also affect visibility in cold or wet conditions. An assessment ensures the underlying fault is identified so your ventilation system can be restored to full working order.

Common signs you need a cabin vent assessment

• No air flow from vents, even with the fan on high
• Air only coming from some vents but not others
• Unusual noises from behind the dashboard when adjusting fan settings
• Strong smells or dust due to a blocked cabin air filter
• Windows failing to demist in winter or humid weather

If you experience these symptoms, a professional inspection can confirm whether the issue is electrical, mechanical, or airflow related.

What happens during an air vents assessment?

A mechanic will test the blower fan, check the cabin air filter, and inspect the vent controls or actuators. Electrical systems, fuses, and wiring are checked, and airflow is measured through the vents. Once the problem is located, the mechanic will provide repair options and a cost estimate.

How much does an air vents not working assessment cost?

In New Zealand, a cabin ventilation or AC assessment typically costs between $90 and $150. If repairs are required — such as replacing a blower motor, actuator, or cabin filter — additional costs will apply. You’ll always receive a clear quote before any repair work begins.

Is it safe to drive if no air comes from the vents?

Yes, your car will still drive, but without airflow, you’ll lose effective heating, cooling, and demisting. This can make driving uncomfortable and may reduce visibility in wet or cold weather. To stay safe and comfortable, it’s best to book an assessment as soon as you notice the issue.
