Faulty relay: If the air vents are not functioning optimally, a faulty relay may be the culprit. A relay is essentially a small current that drives the operation of a larger current. In other words, it controls the latter. Thus, when the relay goes dysfunctional, there will no power to control the vents, halting air circulation in the process.
Faulty blower motor: This component, similar to the blower on a home fan, sends air through the car vents. Like other components, they may become damaged over time, in which case the ventilation system will be negatively affected.
Blown fuse: Electrical components in cars always have some sort of protection to control surging current. This function is usually performed by the switch. Hence a blown fuse will obviously render the circuit defunct and therefore inhibit power supply to the vents.
Problems with the blower resistor: The blower resistors are responsible for helping the blower motor to control the speed of airflow through the car vents. The resistor basically regulates the blower motor output so that you don’t get more air than you want.
Broken hose: Hoses are needed to drive air circulation in a ventilation system, so any clogs, leaks or damage will make the hose ineffective and consequently prevent the vents from working optimally.
The air intake is clogged: Poor circulation may be as a result of clogged air intake. Air intakes can be of two types; fresh and recirculated, where the former involves taken air from outside, and the latter helps to recycle existing air inside the car. When clogged, either of these components will limit the functioning of the ventilation system in your car.
Air vents are an integral component of the ventilation system in all cars. Fully functional vents can pipe in heated, neutral or air-conditioned air. There are also controls that can be used by passengers to determine the type, extent, and direction of airflow. Faulty vents will obviously make it difficult to control air circulation in your car, in which case you may have to rely on the windows to keep car temperature in check as it would be otherwise stuffy to drive. This may also be a reason why hot air is coming out of car vents.
A professional mechanic will inspect the entire ventilation system to find the specific fault. This includes checking the fuse and relay, running the fan, and conducting other necessary tests. A full inspection service will end up with a detailed report of the source and extent of damage, as well as the cost of repairs for parts that may need to be replaced as to why air is not blowing hard out of car vents.
While no significant driving threats may be posed by air not blowing hard out of car vents, the ventilation system is important for comfortable and hassle-free driving. So problems should be addressed when they arise to keep maintain the air circulation ambience in your car. Our expert mechanics are always ready to help. So book an inspection service with one today if you detect any problems.
