My Car Ac is off But Still Blowing Air

Last Updated on June 20, 2023 by Ryan

My car AC being off but still blowing air is likely due to a faulty blower motor or fan relay. The most common issue would be the blower motor resistor which controls the speed of the blower motor and can become worn out over time. This will cause the AC to turn off, but the fan will still blow air at full speed.

Another potential culprit could be a broken wire in your cars wiring harness that connects to either your ac control unit or runs directly from ignition switch to your fan relay on your fuse box causing it not work properly. I would recommend having an automotive service technician diagnose and repair this problem for you as soon as possible so you can get back into comfortable driving again!

If your car is blowing air but the AC isn’t on, it could be a sign of something more serious than just a broken AC. It’s important to have your vehicle inspected by an experienced mechanic as soon as possible in order to identify the cause and prevent further damage. Common issues with car air conditioning systems include low refrigerant levels, compressor failure, fan motor problems, or even electrical wiring issues.

By having these underlying causes identified and repaired quickly, you can avoid costly repairs down the road!

AC is On, But It's Still HOT! Diagnosing Air Conditioning in Your Car or Truck!

Why is My Ac Blowing Air When Off?

This is a common problem and could be caused by several different issues. The most likely cause is that the fan on your air conditioner has stuck in the ‘on’ position, which means it will continue to blow even when you switch off your AC unit. Other possible causes include faulty wiring or a defective capacitor, both of which require professional repair.

If your AC continues to blow after turning it off, it’s best to call an HVAC technician for help diagnosing and fixing the issue before any further damage occurs.

Why is My Ac off But the Fan is Still Running?

This is a common issue with air conditioning units and it can be caused by several different things. The most likely cause is that the AC’s compressor has failed, which means it isn’t producing cold air anymore. Another possible reason could be a blocked or clogged filter, preventing cool air from being released into your home.

Finally, an electrical problem such as a bad capacitor or worn-out wiring could also prevent your AC from working properly while leaving the fan running. If you’re experiencing this issue, it’s best to call in an experienced HVAC technician to inspect your unit and identify the underlying cause of the problem so they can resolve it quickly and efficiently.

It is possible for the air conditioning in your car to be running even when the engine itself is off. This is because some cars are designed with an “idle-on” feature that allows the AC compressor to remain powered after shutting off the vehicle, allowing you to cool down and enjoy comfortable temperatures without having to restart your car. Additionally, this can help preserve fuel economy as you don’t have to start up a cold engine just for a few minutes of cooling.

Thermostat Turned off But Still Blowing Air

If your thermostat is turned off but you’re still feeling air coming out of the vents, it may be due to an issue with your fan. There are a few common causes for this problem, such as faulty wiring or a malfunctioning fan motor. If you suspect that something is wrong with your fan, it’s best to call in a professional HVAC technician so they can diagnose and repair the issue.

Why are My Vents Blowing Air When off

When your vents are blowing air even when the heating or cooling system is off, it can indicate that something is wrong. If this happens, you should have a professional inspect the unit for any problems with the fan motor, blower wheel, or other components. It could also be caused by a defective thermostat or an issue in your ductwork.

In any case, having an expert assess what’s going on will help ensure that your home stays comfortable and energy-efficient all year long.


In conclusion, it is important to remember that you should never ignore an issue with your car’s air conditioning system. If the AC is off but still blowing air, this could be a sign of a more serious underlying issue. It is recommended that you take your car into a reputable auto shop as soon as possible in order to have the problem diagnosed and fixed before any further damage occurs.
