Envision yourself driving through downtown on a beautiful afternoon or a snowy day, when out of nowhere, your dashboard air vents stop functioning. It comes from someone who has experienced it all.
To put it mildly, it’s excruciating. Unlike in the summer, when the temperature outside is mild, the car’s heater is required for peak performance in the winter.
What causes dashboard air vents not to work?
It can be technical to inspect all of the parts of your car’s ventilation system in order to find out what’s wrong with it. These are the likely reasons, so pay close attention to them:
A faulty fuse or relay
If your dashboard air vents aren’t functioning, this is one place to look. If your vehicle’s ventilation fuse is blown, the blower motor won’t be able to do its job of releasing air via the vents.
A broken relay, which supplies current to the blower motor, is another possible cause of this issue in your car. A lack of electricity to activate the blowing motor means that air cannot be expelled.
Low level of refrigerant
This is a typical reason why your car’s air conditioner stops functioning. You should see a marked decrease in the cooling impact of the air blasted into your vehicle when the refrigerant level is low.
The air conditioner could eventually start releasing heated air as a result of this. The air conditioner in your car won’t be able to do its job of cooling the inside if the refrigerant isn’t present.
Jammed air intake
There are two openings that let air into your car. The first section consists of the openings in the windshield’s lower half, while the second section is the air that is recirculated throughout your car.
In order for the air conditioning system in your car to work, these two components are crucial. The vehicle’s ventilation system will be unable to circulate air throughout the vehicle if any of these two openings is obstructed by foreign objects.
Faulty blower motor or resistor
Your car’s ventilation system wouldn’t be complete without the blower motor. This engine powers a fan that sits behind the dashboard and is in charge of distributing air through the vents.
The blower motor’s efficiency could be diminished due to a number of things, such as electrical issues, old age, and so on. But turning on the air vents won’t bring cool or hot air into your car if the blower motor isn’t working.
It is the blower resistor that allows the blow motor to work. When you turn the air vent controls on or off, the blower resistor helps control how much air is forced into your car.
The car heater may not be producing airflow, which can impact the circulation of cold air within the vehicle, if the blower resistor in the ventilation system is defective.
Torn hoses or belts
There are a number of hoses that carry fluid to and from your vehicle’s ventilation system; if any of these hoses get damaged, your ventilation system won’t work. The efficiency of your car’s air conditioner will be diminished if refrigerant leaks due to a ripped hose. Another cause of this problem is a worn or broken belt.
Failed condenser or compressor
You may not be able to get cool air through the vents if the condenser fails. By transforming the refrigerant from a gas into a liquid, the condenser extracts the heat from the gas. Overheating can occur even with the air conditioner turned on if the condenser is broken or clogged and not allowing enough air to reach the unit.
Conclusion
Basically, you need to know what’s causing your dashboard air vents to not work, how to clear them out, and how to solve any other problems they may be having. We have highlighted the recurrent issues, provided professional solutions, and added additional important considerations below. Now that you know how to fix your car, you can fix your dashboard air vents that aren’t working.
