Why Front AC Not Working But Back Is and The Fixes

If you have a front and rear air conditioner in your car, you may have noticed that the front AC is not working but the rear AC is. There are a few things that could be causing this, and there are a few fixes that you can try. Here are the most likely causes and fixes for a front AC that is not working but the rear AC is.

What Cause Front AC Not Working But Back Is Blowing?

There are a few potential causes for why your front AC unit might not be working, but your back one is. One possibility is that the front unit is not receiving power, while the back one is. This could be due to a problem with your home’s electrical system, or it could be an issue with the AC unit itself. Another possibility is that there is a blockage preventing air from flowing into the front unit, while the back unit is not affected. This could be due to a problem with the ductwork or a build-up of debris around the front unit. Finally, it is also possible that the front AC unit is not properly sized for your home, while the back unit is. This could be due to a number of factors, including the size of your home, the climate you live in, and the number of people in your household. If you are unsure of the cause of the problem, it is best to consult with a professional AC technician.

How Do I Fix The Problems?

If your front air conditioner is not working but the back one is, there are a few potential fixes you can try. First, check to see if the front air conditioner is set to the “on” position. If it is, then check to see if the thermostat is set to a temperature that is lower than the current room temperature. If the thermostat is set too high, the air conditioner will not turn on.

Another potential issue could be that the front air conditioner is not receiving power. Check to see if the circuit breaker has tripped. If it has, flip the switch back to the “on” position. You may also want to check the fuse box to see if a fuse has blown.

If the front air conditioner is still not working, it may be low on refrigerant. This is a job that should be done by a professional, as it can be dangerous to work with refrigerant.

Finally, if none of these potential fixes work, you may need to call a professional to come and take a look at your air conditioner.

Clogged AC vents

If your front AC vents are not blowing air but your back vents are, it is likely that your front vents are clogged. There are a few ways to fix this problem:

1. Check the air filter. If it is dirty, replace it with a new one.

2. Clean the AC vents. Use a vacuum cleaner with a brush attachment to remove any dirt or debris that may be blocking the vents.

3. Adjust the airflow. Some AC units have a dial that allows you to adjust the airflow. Make sure that the airflow is set to the highest setting.

4. Call a professional. If you have tried all of the above and your front vents still are not blowing air, it is time to call a professional. They will be able to diagnose the problem and find a solution.

Leakage/low refrigerant

If your front AC unit is not working but your back unit is, it is likely that there is a leakage or low refrigerant issue. To fix this, you will need to check for leaks and replenish the refrigerant.

1. Check for leaks: First, you will need to check for any leaks in the system. You can do this by checking the hoses and connections for any cracks or holes. If you find any leaks, you will need to repair them before proceeding.

2. Replenish refrigerant: Once you have repaired any leaks, you will need to replenish the refrigerant. You can do this by adding more refrigerant to the system.

Bad compressor

A compressor is the main component of an air conditioner, and if it is not working, the entire system will not operate. There are a number of reasons why a compressor may fail, but the most common is due to a loss of refrigerant. This can happen if there is a leak in the system, or if the compressor is not properly sealed. If the compressor is not working, it will not be able to pump the refrigerant through the system, and the air conditioner will not be able to cool the air.

Faulty cooling fan

A cooling fan is an important part of a car’s air conditioning system. The fan helps to circulate cool air throughout the car’s cabin. If the fan is not working properly, the air conditioning system will not be able to properly cool the car.

There are a few things that can cause a cooling fan to stop working. One possibility is a blown fuse. If the fuse that powers the cooling fan has blown, the fan will not be able to operate. Another possibility is a problem with the fan itself. If the fan is not spinning, it will not be able to circulate air.

If the cooling fan is not working, the air conditioning system will not be able to properly cool the car. This can be a problem on hot days, as the car will not be able to maintain a comfortable temperature. If the problem is not fixed, it can also lead to more serious problems, such as engine overheating.

If you think that the cooling fan on your car is not working, the best thing to do is to take it to a mechanic and have them diagnose the problem. They will be able to determine whether the problem is with the fan itself or with something else in the system.

Clean the AC vents

Assuming you have a central air conditioner, there are a few things you can do to clean the AC vents and help improve airflow. First, check the vents themselves and make sure they are clear of any debris or obstructions. If the vents are clogged, this can restrict airflow and make your AC unit work harder than it needs to. You can use a vacuum with a soft brush attachment to gently clear any debris from the vents.

Next, take a look at your air filter and see if it needs to be replaced. A dirty air filter can also restrict airflow and make your AC unit work harder than necessary. Depending on the type of filter you have, you may need to replace it every few months.

Finally, make sure there is nothing blocking the path of airflow from your AC unit to the vents. This includes furniture, rugs, or other items that could be blocking the vents. If you have any items blocking the vents, move them out of the way so that the airflow is not restricted.

Seal refrigerant leakage

If your front air conditioner is not working but your back one is, it is most likely due to a sealed refrigerant leakage. This is a serious problem that needs to be fixed as soon as possible, as it can cause your air conditioner to stop working entirely. There are a few ways to fix this problem, but the most effective way is to hire a professional to do it for you. This will ensure that the job is done properly and that your air conditioner is back up and running in no time.

Replace bad compressor

Your car’s air conditioner is made up of several key components, one of which is the compressor. The compressor is responsible for circulating refrigerant throughout the system. If your compressor is not working properly, it can cause the entire system to fail.

There are several signs that your compressor may be failing. One is that your air conditioner is not blowing cold air. Another is that your air conditioner is making strange noises. If you notice either of these signs, it’s important to take your car to a mechanic as soon as possible.

Replacing a bad compressor is not a difficult task, but it is one that should be left to a professional. A professional mechanic will have the tools and knowledge necessary to properly diagnose the problem and make the necessary repairs.

Must Read

If your front air conditioner is not working but your rear air conditioner is, there are a few possible reasons why. Here are a few tips and tricks to help you troubleshoot the issue so you can get your front AC working again:

1. Check the power. Make sure that the front AC unit is plugged in and that the circuit breaker has not been tripped.

2. Check the thermostat. If the thermostat is set to “Off,” the front AC unit will not turn on.

3. Check the air filter. A dirty air filter can restrict air flow and cause the front AC unit to shut down.

4. Check for debris around the unit. If there is debris blocking the air flow to the unit, it will not operate properly.

5. Check the evaporator coil. If the coil is frozen, it will need to be thawed out before the unit will work again.

6. Check the compressor. If the compressor is not working, the unit will not be able to cool the air.

7. Check for leaks. If there are any refrigerant leaks, the unit will not work properly.

If you have checked all of the above and the front AC unit still is not working, it may be time to call a professional for help.
