It's almost certainly low refrigerant. When the compressor turns on the low pressure side is evacuated, resulting in refrigerant pressure that is low enough to turn off the low pressure switch. As soon as the refrigerant leaks back through from the high side to the low side, the pressure goes up enough to trip the low pressure switch back on, allowing the compressor to run briefly. Just add some refrigerant and you will solve the problem. Most auto parts retail stores will sell you a kit that lets you add a little refrigerant. Add a can to your AC and see how it runs. Use a gauge to add enough for the system to operate at it's optimal level.

My Volvo air conditioning is not cold. What could the problem be?

Air conditioning systems can stop working for several reasons. The most common reason is that the fluid charge has leaked out. Other causes include a disconnected wire, a worn compressor clutch, a broken belt, a seized compressor, a clogged expansion valve, and the list goes on...

How do you troubleshoot your ac in your 1999 mercury tracer?

The air conditioning in a Tracer works through the power relay below the air cleaner. The low pressure switch on the accumulator near the firewall and the high pressure switch near the radiator cross member feed signals to a relay in the power relay box under the air cleaner. This relay box then sends information to the A/C compressor clutch. If you can jack up the car, remove the right front wheel and splash shield, you can "back probe" the wires on the A/C clutch and see if they are getting about 13 volts when the engine is running and the A/C is on. If it has the voltage and the compressor is NOT running, the problem is in the compressor. If it doesn't have the 13 volts, the problem is electrical and is wiring, the relay box or one of the switches, including the dash controls. Good luck eliminating these. To be sure, you can run a wire from ground and the battery directly to the compressor clutch to see if it will engage. If it does, the problem is electrical; if it doesn't, the problem is in the compressor.

Where the air conditioning relay for a 1998 Ford Escort Wagon is The compressor is not starting.?

Most of the relays for the ford escort are located under the hood in a black box with white labelling on it. Also check your underdash fuses. If this doesn't repair the problem, then you might have to replace the air compressor, as they sometimes do set up. The AC compressor relay, and the AC wide-open throttle cut-out relay are in a box under the air cleaner. It is called the multi-function relay. Try tapping on it while the AC switches are on and see if it will start to work.

What causes the air conditioning to go on and off?

More than likely it is short on charge. Best to turn it off until the problem whatever it turns out to be is corrected. Short cycling is not good for the compressor.

Why does your engine stop when you put your air conditioning on?

Check your battery... The A/C Compressor is probably bad. I had the same problem and when you turn on the ac it engages a clutch that is driven by your fan belt and if the compressor is bad it will stop the belt from turning and stall the engine. The same thing will happen for a bad alternator.

How long after repair should you monitor air conditioning system?

If you are facing the problem of low discharge airflow to the cooling space causing low cooling performance which can lead to possible damage to the compressor of the air conditioners.

AC compressor - clutch seems to be locking upmaking noise can only the clutch be replaced or does the entire Compressor need to be replaced?

If the AC pulley is locking up when the ac compressor clutch engages, it's not a clutch problem, it's a compressor problem. But yes, the AC clutch can usually be replaced separately. The problem is, if the clutch is worn out the compressor is probably worn out as well. It usually isn't that much more to replace the whole thing.

Why is air conditioning in the front dash board blows warm air in a 1998 Mercury Villager The rear air conditioning unit works fine.?

I have a similar problem in my 1998 villager that I just bought. If you press the temperature control knob real hard, you will see that the A/C will engage and it will start blowing cold air. The momment you let it go, it switches off the compressor. Based on what I have research so far, its the A/C pressure switch at the back of the temperature control knob that needs to be replaced. I will keep posted once I learn some more about this issue. Good luck!!

When your AC compressor of your 2002 Sebring when warm up make noise when turn on and off specialy in slow traffic what can be done to stop this?

You refrigeration system charge is low causing the low pressure switch to shut the compressor off and on. You will probably find you have a small leak somewhere in the system. Check for leaks around the front condenser coil and around the compressor for wet oily spots. Have the air conditioning system recharged, but if it is leaking, the problem will return.

1988 Lincoln town car air conditioning blowing hot and cold air?

If a 1988 Lincoln Town Car is blowing both hot and cold air when the air conditioning is on, there could be a problem with the thermostat. There might also be a problem with the level of refrigerant in the air conditioning pump.

Why does hot air blow out of the vents on the passenger side of a 2003 Dodge Grand Caravan when the air conditioner is on?

The air conditioner has failed in some way. Either the compressor has failed or the pressurized refrigerant has leaked out. DO NOT operate the air conditioning until the problem has been fixed, the refrigerant contains oil to lubricate the compressor, which, if the refrigerant has escaped, will be damaged without lubrication. Don't turn a cheap fix (refrigerant recharge) into a very expensive one (replace compressor).

Can you remove a seized ac compressor on a 96 Taurus and use a smaller serp belt?

Look fer it!Please Check this out first ---- Unplug the clutch control 1 or 2 wire plug on the front of the compressor and maybe you can keep on trucking with no further modifications needed. The clutch causes a magnetic physical connection to the compressor when it is told to do so by the AC switches or computer circuits sending 12 volts out to make the clutch operate. If the compressor has siezed up and the AC is cut off there would be no problem - but - the defrost position can cut the compressor on also. Try this fix. woody Just wanted to add this: Part number 34166 ($40) is a replacement pulley that mounts in the place of the compressor

You probably need a new air filter for your a/c The clicking is probably caused by the clutch on the compressor. If the Ac isn't charged enough it could cause this to kick the compressor off and on. You compressor could also be bad. You werent real clear what the problem was. Hope this helps.
