There is almost no better feeling than driving your car in extremely hot weather with A/C turned on to max cold. But that cold breeze can rapidly become disgusting instead of refreshing if A/C produces a foul odor. It indicates some poor functioning of the car system. There might be several causes behind burning smells from the car that you might not be able to identify. In fact, this might be the smell of some technical issues in your vehicle. These stinky odors sometimes create an unpleasant feeling not only for the driver but also for the one who is along with you, which can be hazardous. When the rubber pipes under the hood are loose, or are pressed against the hot part of the engine, the rubber part, may start to burn after a while. Identifying the burning smells is crucial to know the cause and find the solution then.

Your A/C Smells Like Vinegar: Sometime when the driver parks the car after a long enough drive, a pungent vinegar smell can be felt, when the car starts to cool down. The pungent smell is strongly noticeable, and the source of that smell may be tricky and sometimes hard to pinpoint. Certain types of molds can cause the car’s air conditioning to smell like vinegar. To remove the bad smell, a vent and duct cleaning does not eliminate the vinegar odor issue, and it is the best option to ask for a professional air conditioner expert.

Your A/C Smells Sweet: If a sweet smell is coming from the car’s a/c, you might not take a big trace. A sweet smell from the car’s a/c could indicate an antifreeze leak in the car’s cooling system. There is a component called ethyleneglycol in the car’s radiator’s antifreeze, which acts as an excellent solute that keeps the water in the radiator from freezing during extreme cold weather. It is also the same substance in the car that gives a sweet smell strangely. The car’s a/c can determine leakage of the cooling system, and if the driver smells something sweet in the car’s a/c, it is necessary for the driver to bring the vehicle for a complete check-up.

The Air Filter Is Clogged: If the air filter of the car’s air conditioning system is not changed regularly, the air filter might get blocked. When the air filter is clogged with too much debris, the airflow is too restricted, putting an extra strain on the car’s A/C motor, fans, and other components of the car’s air conditioning system. As a result, the car’s driver smells a burning smell coming from these components. The driver must check if the air filter is clogged and replace it with a fresh one. Change the air filters each month for good measure and hygienic car drive.

The Capacitor Is Broken: There is a capacitor installed in the car’s Air conditioning system, which works to power the motor. The motor can be overheated if the capacitor is out of order and give off a burning smell. Capacitor lost working for many reasons, from overheated circuitry or power surges to general wear and tear. In such a situation, the car’s driver needs to change the capacitor, and if the situation still remains the same, the driver must call a professional.

To remove the bad smell from the car’s A/C

Different kinds of sprays are used to remove the bad smell from the car due to A/C. These are Turtle Wax Power, Odor eliminator, and refresher spray that can be sprayed directly into Vehicle air conditioner vents to remove the bad smell and other sources of creating a bad smell. Secondly, when the car’s Air conditioning system gives a bad smell, one must point out the source of the smell. The upcoming step is to clean out and sanitize the inside of the HVAC system. To do this sprinkles foam into the vents and up to the drainpipe. Spray the foam thoroughly into the outlet until it starts backing out of the drainpipe. Let the foam soaked into the water for about 20 to 30 minutes, breaking out and draining out of the HVAC system. After performing all these, turn on your car’s ignition switch and run the air conditioner at its maximum speed for about five minutes to make it dry inside of the A/C. After that, take a whiff, and if the smell is still there, repeat the process again. If you have installed a pipe and that pipe is pressed against the hot part of the engine, remove the pipe if needed, also check the condition of the clamps if it seems loose.
