When your car’s AC compressor isn’t turning on, it’s like having a fridge without a motor. Your AC compressor is the heart of your car’s air conditioning system, pumping refrigerant where it needs to go. If it’s not on, your car won’t be able to cool itself down. Not ideal, right?

The Role of the AC Compressor in a Car – Car AC Compressor Not Turning On

The AC compressor is your car’s personal weather station. It takes in refrigerant, compresses it, and circulates it through the system. This is what cools the air that blows out of your vents. If the AC compressor isn’t working, your car’s AC system won’t either.

Common Symptoms of a Car AC Compressor Not Turning On – Car AC Compressor Not Turning On
