What To Do If Air Won’t Come Out of Your Vents 

If you live in a climate that is hot most parts out of the year, then you know how important the air conditioning (AC) in your car is. The AC helps keep your car cool and makes it pleasant to drive in. Without it, driving your car can become very uncomfortable, especially during the summer months.

Keep on reading to find out what to do if your precious AC won’t come out of your car air vents.

Reasons Why Air Will Not Come Out

We’ve all been there. We go to turn on the AC, and we hear it click on, but no air is coming out of the vents. We fiddle with the vents and dials, but still can’t get it to work. Immediately the thought of driving the car on a hot day, without AC becomes anxiety-inducing.

But why won’t the air come out?

Clogged Air Intake

Most vehicles have two air intakes:

  • Fresh air: this intake filters air coming from the outside of the car.
  • Recirculated air: this intake filters and circulates the air already inside the car.

Over time, it’s possible for these air intakes to become clogged. If that is the case, the venting system in your car will not function properly, and you may not feel any air come out of your vents.

Air not coming from the vents

Bad Fuse

The ventilation system in your car relies on an electrical system. Part of that system is a fuse that is in charge of overcurrent protection. In the scenario where the fuse blows, the circuit that powers the ventilation will stop working completely. In which case you’ll be left without air completely.

Dysfunctional Relay

Like fuses, relays play an important role in the electrical system that controls the ventilation system in your car. Relays take small currents in order to control the larger currents the ventilation requires in order to operate. If the relay in the system is bad, the vents will no longer receive the power they need to operate.

Broken Hose

Hoses in the venting system are very important. In fact, there are multiple hoses in the ventilation system for modern cars. They help transfer air, water, and other fluid so the system can function properly. Over time, these hoses are susceptible to wear and tear, such as:

  • Cracks
  • Tears
  • Kinks
  • Clogs

In leaks, clogs or breaks in the hoses will prevent their ability to function properly

Bad Blower Motor

Blower motors are the most important component in an automobile’s ventilation system. The blower motor is responsible for sending air through the vents of your car. Over time, blower motors can become damaged, or completely fail. In which case, air will no longer come out of your vents.

How to Troubleshoot the Issue Yourself

If you would like, you can try to troubleshoot the problem at home. You can follow these simple steps to do so:

  1. Turn the AC on
  2. Check the strength and the temperature of the airflow
  3. Check for any obstructions
  4. Inspect the AC belt
  5. Listen to and inspect the compressor
  6. Double-check the fuses and wiring

If you were unable to identify and fix the problem, and you are still having issues, it may be time to hire a professional.

Hire a Pro To Fix the Vent System

Air not coming out of your vents is not an emergency repair. You are unlikely to cause any more damage to your vehicle if you delay the service.

However, the sooner you can schedule your car for maintenance, the better. The driving experience you have with a functioning ventilation system will be much nicer if you do.
