It's very possible if you've added refrigerant to the system it's been overfilled. Compressors require a minimum of 20psi to work and should not be filled over 40-45 psi unless specified by the manufacturer. Sounds like your system either has a leak and can't hold the refrigerant or has been overfilled, causing the compressor to act up. Post back with any other questions and best of luck.

A/c blows cool air, compressor cycles on and off constantly. Perssure checks good

You may have cold air, but the system is low on charge, give it time and the air temp at the registers will rise and the compressor stop working when the charge gets to low.

05 tc. A/C blows hot then cold. Didn't blow cold

The A/C pump ismade of three seperate components. You are correct in it being electrical, to some degree. The compressor is self turnes, & in turning moves the freon thru the condensor,dryer, evaporator, & condensor. With the engine off, you can grab the clutch on the compressor, & turn it manually. Now, to your question. When you turn on your A/C, it sends a signal to one of 3 parts on your A/C compressor. The 1st signal, is a charge to the magnet (not its nomenclature name) that pulls the clutch, quickly, into the compressor shaft, so it can start turning. Now as this signal, is working,on an intermittant basis, 1 your clutch has been damaged, not always engaging fully,causing disc wear. The activating magnet, works intermittantly, this too, strains the electrical wiring, going thru the compressor to the magnet. Now the compressor works, but, 2 components, have gotten very hot, by intermittant action. To remove them, if "fused", will be labor intensive. Thanhaving a "sealed" system, dis-assembled, then re-assembled on a mechanics work table. No matter how hard I try its never completely clean......the repaired compressor can allow harmful contaminates into a system that works, with one part not working. Once contaminates are in the system......all the components can be damaged. The mechanic, is giving you the most cost efficieant repair, that will last longest, with least possiblility of failure.

Ac doesn/t blow cold air

There could be a leak in your a/c system. Does your a/c compressor engage when the a/c is turned on? To check, locate the compressor, its a big cylinder on the serpentine belt, you should see the wheel engage(spin) and disengage(stop) when the a/c is activated. If it doesn't move, then your compressor is bad. If it does move, then there is a leak in the system that will need to be repaired.

The AC compressor looks like this:

Air suspension not working. no pump sounds

sounds like you have a bad pump. I have fixed dozens of them and 99 percent of the time it is a pump. the other thing is a pump relay or the control module. but not likely.

Ac pump turns on and off constantly. checked pressure of system and ok pressure when pump is off then loss of pressure when on. no cold air at all.

that is a low refrigerant sign you need to charge the system.. the compressor shuts off because the low preasure shutdown switch is triggerd when the compressor starts to move the refrigerant to the high side and shuts off thats why the preasure drops when the compressor clutch engages...

hope this helps.

2005 Jeep GC with 4.7. A/C compressor will not run.

Check the low pressure sensor and the hi pressure sensor to be sure they are operating properly. Also check compressor relay and all fuses.

There must be a gas leak somewhere. Have it checked.

Check your pressures again. Jump the pressure switch and see if this makes the compressor come on. If it does then jump it long enough to get some more freon into the system. This should give switch enough pressure.

Make sure your vacuum is good on the system before you fill.
