What is Wrong with My AC?

We are fast approaching the summer months, which means we are going to be using our car’s AC every day. Being in a situation where you don’t have air conditioning in your car sounds awful, but it happens more often than people realize. If your car’s air conditioner suddenly stops working, it can be incredibly inconvenient. Some of the most common auto ac repair questions that are asked are why the car’s air conditioner stops blowing air, why it stops blowing cold air, or why the AC is blowing hot air. In order to understand more about why your car’s air conditioner stops working, its important to identify the most frequent issues and why they happen. Knowing about these problems will prompt more people to take their cars in for auto AC repair. Below are some of the issues that plague car air conditioners the most.

Why Did My Car AC Stop Blowing Air?

It can be incredibly frustrating when you turn on your car on a hot day only to find that air isn’t blowing through the vents. There are a couple of reasons why your air conditioner might not be blowing any air when you turn on your car.

  • Damaged Relay: In order for the AC’s ventilation system to work, it needs small and large electrical current. The relay is the small current powers the larger current, so when the relay is damaged, the ventilation system isn’t able to work.
  • Defective Resistor: Our air conditioner uses blower motors to move air through the vents. In order for the blower motor to work, it needs a resistor to control how fast or slow the air goes through the vents. When this is broken, air won’t be able to flow through.
  • Broken Blower Motor: Since the blower motor pushes air through the vents, it is an important component to the air conditioner. When it doesn’t work properly, the air won’t be able to go through the vents.
  • Air Intake Clog: There are two types of air intakes, fresh and recirculated. Each of these can become clogged, which causes the ventilation system not to work well.

If your car’s AC isn’t blowing any air, you will need to get auto AC repair, with repairs needed for certain parts. Get in touch with a mechanic for auto ac repair parts.

What Are the Symptoms of a Bad AC Compressor?

The most common reason that your car’s air conditioner might not be working is that the AC compressor might be damaged or defective. The compressor is known as the heart of the air conditioner because it takes freon and pressurizes it, where it will then pass through the AC’s evaporator. Without freon pumping through your car, you won’t have cold air, but warm air flowing through your car. Fortunately, when a compressor starts to fail, it will exhibit certain signs that are specific to a damaged compressor, some of those issues include

  • The clutch for the compressor is not working.
  • The air conditioner is not blowing cool air.
  • There are loud noises coming from the air conditioner.
  • There is fluid leaking from your car.

When your car’s AC compressor isn’t working, your air conditioner isn’t going to function the way that it’s supposed to. To ensure your AC compressor is performing normally, it’s important to get auto AC repair to remedy the issue. An auto ac repair shop will be able to locate the problem and provide your car’s AC with the necessary repairs.

Why Is My Car Blowing Hot Air?

Why is my car air conditioner not blowing cold air? That is the most common question that people will ask in regards to their car’s air conditioner not working. When your air conditioning system isn’t blowing cool air, that is the first sign that you need auto AC repair. There are a couple of reasons why your AC isn’t blowing cool air and instead is blowing warm air. The first reason why your AC isn’t blowing cool air is because it needs a freon recharge. When there isn’t enough freon, the air conditioner’s clucth won’t come on, which will also affect the compressor from cycling. Another reason why your air conditioner is only blowing warm air is because the condenser is broken. The air conditioner condenser converts gas into a liquid, so if its broken or clogged, then your air conditioner won’t blow cool air. Your air conditioner might also have issues if the system has some sort of blockage. When there is a blockage in the air conditioning system, it won’t be able to blow cool air out. Whatever the reason for your car not blowing cool air, it’s important to get auto AC repair to correct the problem.
