The smell can also come from old refrigerant that has turned acidic and corroded the A/C system components. In any case, it’s important to get your vehicle looked at as soon as possible before significant damage occurs so that repairs are not costly.

5 Common types of Burning smell from car but not overheating

Why Does My Ac Smell Like Its Burning?

If you notice your AC has a burning smell, it could be caused by an overheated motor or wiring. This could occur if the fan motor is not running properly, or if there are loose wires in the system that are causing sparks and heat. Additionally, dust may have built up inside the unit over time which can cause friction and eventual burning when air moves through it.

Lastly, burnt-out capacitors on motors can also create a burning smell as they emit smoke while failing to provide power to their respective components. It’s important to contact a professional if you suspect any of these issues so they can inspect and resolve the issue before further damage occurs.

What to Do If Ac Smells Like Burning?

If your air conditioner is emitting a burning smell, it’s important to identify the source of the issue and take steps to remedy it. Start by checking for any visible signs of smoke or fire damage. If you detect any, turn off power to the unit immediately and call a professional repair service as soon as possible.

Otherwise, investigate if there are burnt-out wires in your AC system or if they may have overheated due to clogged filters or other problems with airflow. If so, replacing these components can help resolve the issue quickly before further damage occurs. Finally, make sure that all vents throughout the home are clear of dust and debris; this will ensure optimal performance from your AC system while also preventing unpleasant odors from occurring again in the future.

Can I Drive My Car If It Smells Like Burning Rubber?

No, you should not drive your car if it smells like burning rubber. Burning rubber is a sign of an underlying issue that needs to be addressed by a professional mechanic. The smell could indicate a slipping belt or worn out bearing.

It may also signal something more serious such as an engine misfire or exhaust leak. Driving your car in this condition could make the problem worse and put you at risk for costly repairs down the line. Have a certified mechanic inspect your vehicle immediately to diagnose and fix any issues with the burning rubber smell before driving again.

Burning Smell from Car But Not Overheating

If your car is emitting a burning smell but it isn’t overheating, the likely cause could be worn brake pads or another issue with your brakes. When brakes get too hot from extended use, they can release an unpleasant burning odor that can linger in the air and fill up the cabin of your vehicle if you have poor ventilation. The most important thing to do when you notice this problem is to take your car into a mechanic for proper diagnosis and repair before any further damage occurs.

Car Smells Like Burning Rubber When Ac is on

If your car smells like burning rubber when you turn the AC on, it could be a sign of an issue with one of the components in your vehicle’s air conditioner system. In most cases, this is caused by a worn out belt that connects to the compressor or pulleys, and needs to be replaced as soon as possible. If left unchecked, this can lead to more costly repairs and potential safety risks due to decreased airflow from the vents.

It’s important to have your vehicle inspected immediately if you experience this odor when running the AC so that any necessary repairs can be made before further damage occurs.

Burning Smell from Car Ac Not Working

If your car’s air conditioner is producing a burning smell, it could be an indication of a problem with the blower motor. The blower motor pulls in and blows out air from the AC system. If there is debris or dirt stuck somewhere inside the fan blades, this can cause heat to build up and produce a burning smell.

It may also indicate that the cooling coils are overheating due to lack of lubrication or too much pressure on them. In either case, you should have your car checked by a certified mechanic as soon as possible to prevent further damage to your vehicle.


In conclusion, it is important to take action when your car AC emits a burning smell. There are several potential causes of the odor, and it could be indicative of an underlying mechanical issue that needs to be addressed. You should contact a mechanic or auto shop as soon as possible if you detect this unpleasant odor in order to avoid further damage and potentially costly repairs.

Taking care of the problem quickly can help ensure that you get back on the road without any further issues.
