Why is my car’s air conditioner smelling bad? How do I get rid of it?
It’s not fun to get in your car and discover that the AC has a bad odour. It doesn’t matter if you are going to work, or if you’re on a long journey out of town. But, you have to deal with it, especially in certain cases depending on the scent.
What should you do if your car’s air conditioner is smelling bad?
The sense of smell can be an invaluable tool in diagnosing a potential issue with your car. A good way to use this all-too neglected skill is by sniffing the air and trying to match what you find there with one of three different types of smells: Burning, Musty or Rotten Eggs. The first type may indicate that wiring has overheated; while mustiness signifies mold growth due either to condensation on windows or leaks inside the vehicle itself; lastly, rotten eggs indicates that sulfur gas is being emitted from some sorta fuel system leak – time for repairs!

The way we perceive smells is subjective. People often describe the same smell as something completely different. It doesn’t matter what your car smells like, but it is important to do a thorough diagnostic. Here’s what different smells usually mean.
My car’s air conditioner smells like gas
If your car’s air conditioner smells like gas then you could have a leak. The reason the smell intensifies when AC is on is because that fresh air sucks in the leaking odor and pumps it right back to you! If this isn’t taken care of as soon possible there are several different areas where leaks can come from such as hoses or seals which need repaired ASAP before they lead to more significant problems – so keep checking around for any fuel-like scents coming out of vents!.
This passage addresses what happens when your vehicle has a release of gasoline fumes into its system while being operated with the engine off; also called “evaporative emissions.” You must immediately address any gas leaks. You should inspect all possible gas leaks in your vehicle.
- To check if there is a leak, first inspect the fuel pressure regulator.
- Next, take a look at the “O” rings of the fuel injector in the engine compartment.
- Last but not least, check the exhaust pipes for holes and the exhaust muffler.
You can find gas leaks in any of these locations, so make sure to check the others as well. It is possible for more than one gas leak to occur.
My car’s air conditioner smells like chemical
When you’re driving your car and suddenly start to notice a strange scent coming from the AC, then it’s likely that something is wrong with the refrigerant/antifreeze. For many people this also smells sweet as if they had dropped some candy on their engine while working underneath – but don’t worry! There are ways for you to identify what specifically might be going on in there so that we can get things fixed up before any major damage sets in.
You can also get this type of leak from any of the following locations:
- The coolant housing unit
- The heater core
- Any pipe or tube
There are many places that you will need to inspect, but you must check them all as ethylene glycol can be very toxic.
My car’s air conditioner smells like vinegar
One of the more common smells people sense is that of vinegar. It can also smell like food or, even worse, your car’s air conditioner might start to stink like urine! Is it wet socks?
All these types of smells are usually due to mold and mildew building up in your car. The reason they feel different could be because there are so many kinds out there – some more dangerous than others. No matter what type you’re dealing with though; it’s a good idea just get rid of them as soon as possible. Although in most cases the mold doesn’t pose any serious threat to your health, it can still be a problem for the ventilation system. You’ll need to inspect several spots again.
- The AC evaporator in your car is located behind the dash panel
- One or more AC drain holes
- Mold can build up in the air filters of your vehicle’s AC.
Mold is usually a simple problem to fix since you don’t need to replace damaged parts. Turn on the AC and open all the vents. Next, turn off the fan so that it draws air from outside. Open up your windows and spray Lysol or another good disinfectant into the vents.
Spray the entire can of disinfectant in the suction vents while the AC is on. Make sure you put it in both the passenger and driver’s intake vents. You can then leave the vehicle to run for approximately 10 minutes.
My car’s air conditioner smells like burned plastic
If you smell burning rubber or plastic, it is usually a sign that something has been irreparably damaged. It could be the fan, electrical wiring, or the driving belt. If the smell intensifies, it could also indicate a worn clutch.
If you notice any of these things, it is important to have your car inspected by a professional as they can lead to serious accidents.
There are other causes that can cause such smells. These include a burning plastic bag in your car’s interior, antifreeze leaks, and the heater burning off any dust. This means that the smell could be either very serious or not so significant. It is worth a thorough and immediate inspection.
