Auto Air Conditioning & Heater Repair: Dodge Ram airconditioning 1994, vacuum pump, orifice tube

Question
My air compresspors cluthc clicks on and off on a very short cycle  Maybe on for  5 second and off for 10 seconds.

I check the level on the low side and add some seems to be right wear it shold be.

Is it a sensor or is it the compresspor/clutch

Answer
You need to have a set of AC gages installed on your AC system to see where your pressures are at. You may only need to:

remove the freon.

evacuate all the air from the system with a vacuum pump.

Replace the orifice tube.

Recharge the system.
