Car aircon problem #4: Car aircon smells bad
As mentioned above, the automotive air conditioning system is supposed to filter polluted air, providing the cabin with fresh ambiance. Therefore, if your A/C produces bad smell instead of fresh air, there are definitely problems.
In order to diagnose this car air conditioning problem, you need to detect which kind of smell blowing out of your car A/C.
Regularly cleaning the A/C helps maintain pleasant air inside the vehicle
Sweet or chemical smell
There are various crucial components that constitute an automotive air conditioner, for instance, heater core and radiator. The radiator, in particular, is responsible for cooling down the system using some kind of coolant fluid which is a sweet-smelling mixture made from different chemical materials.
If you detect such odor in your car after you turn the A/C on, there is probably a leak somewhere in the A/C system. Unfortunately, this sign usually indicates that you might have to replace some components. We would not suggest you to fix this issue yourself but bring it to a trusted service center to have it inspected properly.
This kind of bad smell is most usually found in old cars and those that have not been used for a long period of time. Old cars with high mileage and irregularly-used cars are often left in hot and humid conditions, which allows bacteria to grow and causes damp smell for the vehicle.
Make sure you have your car washed regularly to avoid unnecessary issues and use your car at least twice a week to protect its critical parts.
Such odor normally indicates that there are some parts of your A/C are being stuck up and covered in dirt and dust. Sometimes, you can also find stagnant water in it. The solution to this problem is very simple. Instead of turning off the A/C to temporarily get rid of the irritating odor, all you have to do to completely address this problem is to have the entire A/C system leaned up.
