Couple of things:

When testing make sure the AC is on MAX and recirculate, and the car is running :)

Try to test when the car has not be running i.e.: operating temp

Sometimes, the cabin air filter, usually behind the glove box, if it is occluded it will cause issues.


Also, Schrader valves are known to fail, this may be the issue you are having on the low side reading.

Edit: I’ve heard of the switch for the clutch not working when it gets warm. It’s the switch to engage the magnetic clutch.

Check pressure in the system. Too high or low. I’m leaning towards low with it coming on and off.

Refrigerant leaks: Loss of refrigerant through leaks will cause multiple problems for an air conditioning system. One of the major signs that a leak has occurred is when the AC begins to short-cycle. Since low refrigerant is an immediate threat to a compressor.

Check your air filter. Believe it or not, a clogged air filter can cause a wide variety of air conditioning issues. ... Check your thermostat placement. ... Check your air conditioner's refrigerant levels. ... Replace the low-pressure control switch. ... Check the compressor.
