Why did my Subaru AC suddenly stop working?

Possible Reasons for Subaru AC Not Working
There could be several reasons why your Subaru AC suddenly stopped working. Here are some possible causes based on the search results:
1. Refrigerant Leak: One common reason for AC failure in Subarus is a refrigerant leak. Over time, Subarus can lose between 3 to 5 percent of the R134a type refrigerant in the system every year. If you haven’t recharged your air conditioning in a few years, you may not have enough refrigerant to cool your Subaru.
2. AC Compressor Failure: The AC compressor is an important component of the AC system. It pressurizes the refrigerant and keeps it flowing to cool the car’s interior. Subaru AC compressors can fail in two ways: the electronic clutch that engages the compressor can fail, or the bearings inside the compressor can fail, causing the pulley to make loud noises or lock up.
3. Blower Motor Issues: If there is no air flow or reduced air flow from the vents in your Subaru, a bad blower motor could be the culprit. A worn-out or weakened blower motor can also produce abnormal sounds when in operation. In this case, the blower motor needs to be replaced with a new one.
4. Electrical Issues: There could be electrical issues at the control module for the AC unit, causing the system to believe the AC is on or off when it’s not working. In some cases, replacing the climate control/radio unit with a low-mile OEM unit has fixed the issue.
It’s important to note that these are just possible reasons for the AC failure. To accurately diagnose and fix the issue, it is recommended to schedule a service appointment with a Subaru dealership or a qualified mechanic.

Why is my AC compressor not working but the fan is running?

If your AC compressor isn’t working while the fan is running, there are a few potential reasons. First, check the circuit breaker to ensure it hasn’t tripped. If that’s not the issue, it could be a problem with the capacitor, relay, or the compressor itself.

How much does it cost to recharge a car AC?

A professional AC recharge cost ranges from $150 – $300 on average depending on the make and model of your vehicle.

How do I reset my air conditioner?

How do you reset your AC unit?

1. Turn off your air conditioning system using the thermostat.
2. Search for the breaker box.
3. Shut off your AC unit at the breaker.
4. Wait at least a full minute before switching the breaker back to the “on” position.
5. Wait for 30 minutes before turning your unit back on at the thermostat.

What is the first thing to check when the AC stops working?

Look at your circuit breakers and see if the circuit the AC is on may have flipped. Then, switch the breaker back to the “on” position to deliver power to your unit again. Making sure the outside unit’s disconnect switch has not been turned off. This can sometimes occur when someone is doing maintenance.

Why is my AC blowing hot air Subaru?

Clogged Systems
With time, some parts of your system can get clogged with dust, debris and other particles. This blocks overall airflow as well as the flow of refrigerant resulting in the system blowing hot air.

How do you diagnose a car AC problem?

Start your vehicle and turn on the AC with the fan on high. Then, cycle through the selector options on your HVAC control, feeling for cold air from each position. Positions that don’t blow cold air may have a temperature sensor issue, while positions that don’t blow any air might have a blend door actuator problem.

Why is the AC in my Subaru not working?

The first possibility is that there is a refrigerant leak. The leak may be found in the evaporator, condenser or hose in which case you should bring your car to a mechanic to be repaired. Another reason that your air conditioner may not be blowing cool air is because the compressor has gone bad.

Why did my air conditioner stop working out of nowhere?

There are a few reasons why this might happen. Some of the simpler causes may be that a vent is closed, or that the thermostat needs fixing. Some more major causes may be that the unit is low on refrigerant, signaling a leak, or that there is a problem with the fan.

Why did my AC suddenly stop in my car?

So what caused your air conditioner to stop working? Most likely, your AC system lost its charge of refrigerant. Or, due to an electrical fault, its compressor is not engaging when you turn on the system. Another possibility is that an internal obstruction is blocking the circulation of refrigerant.

Why did my car AC stop working out of nowhere?

Why is my car air conditioner not blowing cold air? There can be a number of reasons why you can air conditioning is not blowing cold air. The most common reasons could be a clogged filter, cooling fan problem, radiator trouble, or it could simply be that you need to recharge (regas) your air conditioning.
