What does it mean when your AC only blows hot air?

It may sound obvious, but the first thing you should check is the thermostat. If your AC is blowing hot air, the thermostat may have been accidentally set to “heat.” If this is the case, it’s easy to fix on your own. The “on” function means the fan will run 24/7 to circulate the air, even if the AC or heater is off.

Try cleaning your air conditioner’s filter and the coils to see if improving the airflow fixes the problem.

Why is my Jeep Cherokee not blowing cold air?

One consistent thing I’ve read is to check how the compressor clutch reacts when you turn on AC – if it disengages then it doesn’t have enough pressure and likely has a refrigerant leak. My 94 Cherokee (apparently not great AC systems to begin with) seems to be blowing only slightly cool air when AC is on max settings.

How does the air compressor in a car work?

Some car compressors use a clutch inside the air compressor. The serpentine belt powers the air compressor pulley, and when you activate the AC – the clutch is connecting the air compressor to the pulley. This makes the AC compressor to spin and power the AC system.

When does the air compressor kick on and off?

If the system were where it is supposed to be, the compressor would kick on/off constantly once the system has been run for a little while. This happens after the pressures get to where they need to be on each side of the system (high/low).
