Air conditioning problems in Honda CR-V vehicles might happen more often than not but in most cases, they are usually not too serious. All you would need is dedication and some time to get things fixed and the AC working again.
However, in other cases, it could signal a serious problem that would require you to replace some parts of the system. This could be the compressor or the clutch which are the common causes of serious AC failure.
If you’re A/C is not working, you’re not feeling any airflow from the vents, or you’re just getting a low-pressure chill that doesn’t make for much, you will find all the causes of such problems and the right fixes to apply in this article.
Honda CRV AC Not Working: Common Causes
- Low level of coolant
- Blown fuse
- Faulty blower motor
- Faulty air conditioning wiring
Honda CRV AC Not Working: Tips on How to Fix
Check the Coolant Level
If you notice that the pressure from the vents is very low but you can still feel the cold from the air, there are chances that your car would be running low on coolant. There could be other reasons to this but having low level of coolant is most likely.
To check the coolant level, lift the hood of the car. You will find the reservoir in front of the vehicle in the shape of a plastic white jug. Remove the light and shine a flashlight into it. The jug has a low line (min line) and a full line (max line). If the coolant is below the min line or max line, then you would have to top it to the necessary level
Before topping up the coolant, you should first confirm that your coolant level is not dropping due to a leak. Leaks could be in the hoses, radiator or radiator cap so you need to inspect these and other parts of the cooling system to confirm that there is no leak anywhere. You could also use a UV kit to check for leaks and if any, you should get a mechanic to have the affected parts replaced.
Topping up coolant is very easy but you should take the necessary precautions to avoid injuries. Avoid removing the radiator cap while the engine is still running or hot. This could cause the coolant to spray out and scald you. Instead, let the engine and radiator cool before removing the radiator cap
When topping coolant, you should ensure that the level is between the low line and the full line. Avoid spilling coolant and if such happens, you should wipe it off immediately.
With the coolant topped, you should once again check for leaks.
Check and Replace any Blown Fuses
The AC system is controlled by a fuse that prevents damage due to over-current. If the AC system is not working, it could be likely that the fuse controlling the system has blown.
To confirm this, you would have to open the interior fuse box the check the fuse.
Open the driver’s door and remove the trim panel right to the side of the steering wheel. You can consult the user’s manual to know which of the fuses control the AC system. Once seen, you would have to inspect it to see if has blown. The fuse would have to be replaced to get the AC working again. However, if there is nothing wrong with the fuse, then you might need to check the AC system wiring.
Check the Blower Motor
If you’re not getting any air flow from the vents then, you might be dealing with a faulty blower motor. You should be able to find the blower motor by prying the lower foot panel on the passenger’s side. Unplug all electrical connectors and pull the blower motor downward.
When it comes to blower problems, you could be dealing with faulty wiring, a blown fuse or a failed motor.
You can diagnose this problem by checking each of these three parts. You can start with the fuse.
Check the fuse box for the fuse linked to the blower motor. Inspect it to see if it has blown. If so, then it would have to be replaced with a new fuse of the same rating.
You can also inspect the blower motor for faulty wiring. Any repair or replacement would have to be handled by a mechanic, but if you know what you’re doing then you can repair or replace any faulty wires.
If the wiring looks great and the fuse is in good condition, then it is likely that the motor just failed and would have to be replaced. This would incur some costs so you should have a mechanic check the vehicle to confirm that the blower motor needs to be replaced before going ahead.
Check the Compressor
This is not very likely but it could happen. If you’re noticing issues with the AC system, it could be due to a faulty compressor. The compressor is a vital component of the AC system and without it, the system would fail to function.
You might have to inspect the compressor to see if it is faulty. You would have to check if there is power supply to the compressor and if the compressor belt is in good condition. If both check out, then it is likely that the compressor failed and would have to be replaced.
However, if there is no power to the compressor, then you would have to get the car to a mechanic. There are a bunch of reasons why the compressor isn’t getting power and you would need your mechanic to help you narrow them down.
Detailed above are the most common problems that could affect your Honda CR-V AC. You can start by checking the coolant and then the compressor. In most cases, the problem can be handled by topping the coolant level and replacing the fuse. If it is a serious problem or something you can’t handle, then you should get your mechanic to inspect the system and save you time.
