Inconsistent cooling. The AC compressor is powered by the relay. If it is not functioning properly, then the AC system will not be able to produce cold air correctly. When a relay is starting to fail, it may give weakened or intermittent power to the compressor, which will result in weakened or intermittent function of the AC.

GM and others use either a three-relay set up to run the two fans at low speed for normal driving and high speed when the AC is on or the low speed can adequately cool the radiator. Other carmakers use a solid-state speed relay that varies the speed of the fans based on engine cooling and AC needs.

How long does an intermittent air conditioner last?
When the AC first begins intermittent failure, it may function properly for as long as 30 minutes before cutting off. But as the clutch wears further down, this time span decreases. Depending on how long this problem has existed, the clutch may only remain engaged for the first few seconds before it slips and disengages the air conditioner.
What happens when an AC unit runs out of refrigerant?
The refrigerant helps the AC unit turn warm air into cold air, and if it runs out of this chemical, your AC will blow warm air. When the refrigerant leaks out, it not only increases the potential harmful health concerns but also increases your energy consumption.
Why does my car AC keep blowing cold air?
Cold Air Blows Intermittently. Intermittent cooling is often caused by the components of your vehicle’s AC system freezing up. Typically an iced over evaporator is the culprit. An evaporator covered in ice can’t cool the air, so you would have to wait until the ice melts, which is why the cold air eventually returns.
