When a car air conditioner compressor keeps running after being turned off, it is most likely due to an issue with the electrical system.
This could be caused by a faulty relay or fuse, or a loose wire connection.
It can also be due to an issue with the pressure switch that is designed to turn off the compressor when the correct amount of pressure has been reached within the air conditioning system.
Why Does My Car Air Conditioner Keep Running After I Turn It Off?
It can be extremely frustrating when you turn off your car’s air conditioner only to have it keep running after you do so.
This is a common issue and one that has a few potential causes.
One reason could be that the blower motor, which is responsible for blowing cool air out of the vents, is malfunctioning or defective.
Another cause may be that the AC compressor clutch isn’t disengaging properly after being turned off, causing the system to remain in operation even when it should be shut down.
Finally, there may simply not be enough refrigerant in your system, which would prevent it from cooling as efficiently as it should and would thus require more energy to run than normal.
Whatever the case may be, if this problem persists then it’s best to take your car to an auto repair shop right away so they can diagnose and fix whatever underlying issue might exist with your vehicle’s A/C system!
What Does It Mean When the AC Compressor Stays Engaged?
When the compressor stays engaged or “on” continuously, it means that your air conditioner isn’t cycling off when it should.
This could be due to a few different issues such as a faulty thermostat, low refrigerant levels, or even an issue with one of the components within the AC unit itself.
If this happens, you’ll want to bring in a professional HVAC technician right away to diagnose and repair any problems you may have before they become bigger (and more expensive) down the line.

Car Air Conditioner Fan Keeps Running When Turned off
If you find that your car’s air conditioner fan keeps running even after you’ve turned it off, this could be an indication of a problem with the blower motor or its associated wiring.
To get to the root of the issue, have a qualified mechanic inspect and diagnose what is causing the fan to stay on when you turn it off.
My Car is off But the Ac is Still Running
If your car is off but the air conditioning system is still running, it might be an indication that there’s a problem with either the electrical system or the cooling fan.
In some cases, this could be caused by a faulty relay switch in the engine bay which keeps supplying power to certain components even after you’ve turned off your vehicle.
Car Ac Compressor Not Turning off
A car AC compressor not turning off is usually caused by a faulty relay or electrical issue.
Low refrigerant levels, an overcharged system, a bad thermostat, or an incorrect fan speed setting can also cause it.
If the problem persists after checking these potential sources of trouble, it’s best to take your car to a professional mechanic for repair as soon as possible.
