With the summer heat approaching its peak, not having a working air conditioner in your car can make even the shortest commutes frustrating. Opening your windows can help, but more often than not, it makes the situation worse. If you find yourself without operating AC vents in your car, consider one of these several reasons to explain why this might be happening. Understanding the issues before bringing your vehicle to an auto mechanic in Madison, TN can help you to evaluate the cost you can expect to endure with your repairs.
A Blown Fuse
Similar to your home air conditioning units, your vehicle’s AC system requires electricity in order to run. If a fuse has been blown in the car’s ventilation system, then your vents won’t be able to blow air out, hot or cold. Having a blown fuse won’t necessarily mean that other components that rely on electricity won’t work, so it’s best to have a professional analyze the situation.
A Damaged Motor
Your car’s blower motor is responsible for blowing air through the vents, so when that gets damaged or stops working, you will notice that your air conditioning system no longer works. These motors can die after years of use or can break if a foreign object gets lodged in the vents. Either way, it’s a simple thing to have replaced by an auto mechanic.
A Faulty Relay
A relay is an electrical component necessary for your car’s AC vents to function. It’s responsible for sending a small electric current used to control the vents. When this stops working properly, you will start to see issues with your vents, and they will ultimately stop working.
A Broken Blower Resistor
Part of the blower motor’s ability to function is the blower resistor, which ultimately controls air flow. This is the component that allows you to crank your AC up on those especially humid days. When this piece stops functioning, so will the vent motor and ultimately your vents.
A Broken Hose
Your vehicle’s air conditioning system requires several hoses to function. If any of them are leaking or broken, it will affect how your AC functions. Certain hoses will cause the vents to stop working and can be a quick and easy fix by a professional.
Clogged Air Intake
Your car has two air intake functions: one where it circulates air internally, and another where it gets air from outside. If either of these gets clogged by debris or fluids, even partially, you will notice that your vents aren’t working to their best ability. This can ultimately result in your car vents failing to work altogether.
