Honda CRV AC Not Working

Air conditioning is one of the last things that you want to face when you are driving on a hot day. If your Honda CRV’s AC is not working, there are a few issues that could be behind your AC not working properly on your CRV. The good news is that most are simple to fix.

One possible reason your Honda CRV’s AC isn’t working could be due to a low refrigerant level. This issue arises when there’s a leak in the AC system, preventing it from cooling the air effectively. The solution is to locate and repair the leak, then recharge the system with the correct amount of refrigerant.

Another common culprit behind AC issues in a Honda CRV is a malfunctioning AC compressor. The compressor is the heart of your car’s air conditioning system, circulating refrigerant and pushing the cool air through. Imagine your AC system as a cyclist in a race; if the cyclist (compressor) can’t pedal, the bike (AC system) won’t move forward. To fix this, you may need to replace the compressor to ensure that cool air starts flowing again.

Finally, a clogged cabin air filter can also lead to ineffective cooling. Over time, the filter can become filled with dust, leaves, and other debris, blocking the flow of air. It’s like trying to breathe through a straw clogged with cotton; air flow is significantly reduced. Replacing the cabin air filter is a simple and cost-effective solution that can restore the efficiency of your AC system, ensuring a cooler and more pleasant driving experience.

Honda CRV AC Not Cold Enough/Cooling

Occasionally, when you go to turn on your Honda CRV AC you may notice that while it is blowing out cool air, the air temperature will not change if you try to make it even cooler. This could be either an issue with fluids or with your air compressor. 

If your Honda CRV AC is not blowing air that is cool enough, you should first check your fluid levels. Make sure that there are no leaks in your refrigeration system. If you do not detect any leaks, it could be related to an issue with your AC compressor leaking. How cool your AC can get depends on the PSI of your AC compressor unit.

If there are any leaks then the PSI will not get to the correct level and your cooling will be compromised.

Honda CRV AC Not Blowing Cold Air

An unfortunate problem to run into on a hot day is when your AC is blowing air that is not cold. The first thing to do is to check the PSI on your AC compressor. Using a set of gages, you need to measure both the high side and the low side of your compressor to determine if it is working properly. You want to see a PSI that is around, or a little above, the temperature that is outside.

If your Honda CRV AC is not blowing cold air and your PSI is below the desired range, then you most likely leak coming from your compressor. When the pressure drops to a low enough level, your car will no longer turn on the AC compressor, preventing you from getting cold airflow.

After you’ve checked your AC air compressor, the next spot to look at is the fuse box. Your AC compressor relay fuse will be in the fuse box that is located under the hood of your car. On the underside of your fuse box, you will see a labeled map that will let you know exactly what fuse to look for. You want to remove the relay from the fuse and test each of the connections with a volt detector to make sure they are responsive. 

Honda CRV AC Not Working at Idle

If you find that your Honda CRV AC stops working when you are idling, there are a few common issues that can cause this problem. When your car is idling, it purposely isn’t putting out much power. That means that issues that may be simple can be more prevalent when they are in this state.

If your Honda CRV AC is not working when your car is idling, you may be experiencing a poor functioning compressor due to debris. 

Honda CRV AC Not Turning On

When you turn the dial to turn your AC on, usually you can hear a slight click. This is the AC compressor clutch engaging and starting the AC. If you do not hear this click, or if your air simply will not turn on, you may be facing an issue with your AC compressor.

If your Honda CRV AC is not turned on, the first place to look is at your AC compressor. Check to see check to make sure that the AC compressor clutch is properly attached and has not sustained any damage. If it is damaged, you will need to replace it. The next spot to look is at the compressor itself.

If your AC compressor has a PSI that is too low, that indicates that there is a leak in your AC compressor. If this is the case, your Honda CRV’s computer will not allow the AC to turn on until the leak has been fixed. 

Honda CRV AC Not Working When Hot Outside

You may notice that you have a fully functioning AC the majority of the time except for when it’s hot outside, which can be frustrating, to say the least. There are a few causes that could be behind this issue.

If your Honda CRV AC is not working when it is hot outside, you should first check to ensure that there are no leaks in the refrigeration system. If you are losing coolant, the hotter it gets outside, the less fuel your AC compressor will have to keep you cool. If you do not detect any leaks, it’s time to look for anything that could be causing issues with airflow.

Check both your air filters and your evaporator to ensure that they are not dirty or clogged. Next look at your air compressor and test to see if it is experiencing any leaks. If it is leaking, your Honda CRV will only allow it to operate at a certain level. If the temperatures outside are hotter than the PSI, your AC will stop working.

Honda CRV AC Loud Noise

If you turn on the AC in your Honda CRV and there is a loud rattling or it sounds like your fan is working at a higher speed, that’s an indicator that your AC is having to work too hard. Hearing noise from your AC system is a sign that something needs to be fixed.

If you hear a loud noise when you turn on your Honda CRV, the first thing that you should check is your fan motor. If your fan motor is dirty or is worn down. You can add a little grease to your fan motor if it isn’t too damaged. Open the vents in your car and try turning the air conditioning on. 

You may need to replace your fan motor if the problem still persists. Another common sound is a clicking noise when your AC turns on. If it is a quiet click that does not continue after your AC has started, it’s nothing to worry about. If the noise continues or gets louder, you are more than likely to face an issue with your AC compressor. 

If the noise you are hearing is more like a hissing, this usually means that you’re experiencing a leak or are low in your AC refrigeration system. You can first eliminate a system leak by first refilling the AC gas levels. If the levels are full, you can check for where the leak is and patch it.

Honda CRV AC Not Working

If your Honda CRV AC is not working it usually comes down to some very common problems that you can fix on your own without taking your car into the shop. When assessing your AC, first look at the compressor to ensure that everything is attached correctly, there are no leaks or other damage.
