Check first for leaks by using soap suds over the lines for the high and low of the AC system. An obvious sign of leak is oil coming out of the line or valves or at the AC compressor itself. If there are none then start the engine, set the AC and blower to high and connect the pressure gauge (make sure you have the dual one for the high and low so you can address both at once) and start adding freon.
If you only have a single gauge, have it connected to the low pressure side. See video below for additional reference.

Hi,

I always discourage people from repairing any A/C work unless trained prior. Not only is the refrigerant bad for the air we breathe if it's released into the atmosphere but you can serious hurt yourself as the stuff is under pressure and if can give you frostbite if it gets on bare skin.
Here's the thing, the refrigerant isn't suppose to go low on it's own. It leaks out. "recharging it" doesn't fix the problem it just makes it work awhile. You need to find the leak and that's usually done by adding an amount of refrigerant to the system and then using a refrigerant sniffer or leak checker to find the leak.

I recommend taking your car to an A/C shop to be fixed right.Whatever you do don't go and buy a "recharge kit" from the auto parts store and just charge it. Most of the time these kits have junk in the refrigerant like dye and extra oil the system doesn't need and it makes things worse.


Let me know,if needed further assistance.

Hope i helped you.

Thanks for using ' Fixya ' and have a nice day!!

    Thanks for your response!!

    I never discourage people from DIY. The fact that i am here is that i love people to save money. However, there are certain situations which is best suited for a technician. A small mistake could result in loss. There are people who are aware of the pros and cons, however there are few who might risk their life trying to follow a DIY.

    Freon leak is a common problem that could be there. Other than this did you jump the compressor and put the correct amount of freon in
    it? Then you need to remove both battery cables and touch them together tp reset the
    low refrigerant warning.


    Once the computer detects a low or high pressure system in the Air
    conditioning system, it will keep the compressor off to protect it from
    damage. You must clear the code in the computer to allow the compressor
    to kick back on.

    To clear the codes on a digital cluster,
    you will use the buttons on the ac control unit. Follow the flow chart
    below to read and clear the codes.





    To clear the codes on an analog cluster, you will have to use the flow chart shown below.




    Let me know,once you check the above details.

    Hope i helped you.

How do i get my ac to work on my 94 honda accord?


You did not say you had check the Freon level or the low pressure switch on the dryer. The low pressure switch will shut down the compressor when it is low on Freon. Hope this helps.

Where is the low ac port on 1999 Mitsubishi gst


The charging port is in the low side AC line from the AC compressor on the engine, the low side line is the larger of the two lines coming from the AC compressor.

Where is the freon refill located at in the ford 2000 expedition?


hi, the freon refill point you are looking for is on the accumulator. but you can't see it cause it's buried by the heater hoses, battery cables, and firewall mounted fuseblock. remove the fuse block cover, and get a bright flashlight, look just below the fuse block and you will see the cylindrical accumulator(aluminum canister looking) and the low side pressure port with the plastic cap on it.

My ac wont get cool.......it blows hot air and(caddy seville 95)


Below is a guide to troubleshoot and check system function. This can be done by most folks.

Look at the front of the ac compressor and have someone turn on the ac from inside the car. The front of the pulley(clutch) will spin when turned on.

If it does not spin, the low pressure switch (LPS) is not satisfied. Meaning there is not enough freon in the system to operate the system. Means low freon capicity because of a leak.

The LPS can be jumpered to cause the compressor to run (clutch to engaged) which will draw the freon in the system.

The LPS is usually a two wire sensor on the suction of the compressor. (between evaporator and compressor) Unplug the sensor and install a jumper, this will engage the clutch. Connect a new can of freon
and fill to system capacity.

The capacity of the ac system will be on a label under the hood, do not overfill. Probably about 2 lbs. Local parts stores (Auto Zone and Advance) will have freon with stop leak. This may help the leak. They also make a freon with a UV dye. I always add a single can with dye so that if stop leak does not work I can find the leak in the future.

The system should be filled until suction pressure is about 30 to 38 psi..

Remember the flow for the a/c system is :
1. From the compressor a high pressure (HP) gas goes to the condenser in front of the radiator.
2. From the condenser a HP liquid goes to an expansion device (orifice tube or expansion valve)
3. From expansion device the low pressure gas enters the firewall to the evaporator.
4. From evaporator the low pressure liquid/gas mixture goes through the dryer2_bing.gif back to the compressor suction.

Where does the freon go for a 99 expedition


Hi .. I just ran into the same problem .. I have a 2000 Expedition with the 5.4L engine .. the low side port is located on the passenger side of engine compartment just below the black metal bracket that contains electrical connections right in front of the firewall... you have to reach under this and locate the low side (larger line) and feel for the connection .. it is right in front of the accumulator .. There are two heater hose that hide the port .. you have reach under these to unscrew the port cap which is black .. you'll have to do this by feel .. I have found that you can by R134A charge with dye and leak sealant helps with small leaks .. if the system takes more than two cans be usre to add refrig. oil .. hope this helps

A.C compressor reads off on my dash. Also I refilled my refriderant and it didnt work. I own A 97 Cadillac Seville STS.


If it builds up too much pressure in the system it will shut off compressor. May be an AC pressure switch problem if compressor does not even come on.

Air conditioning won't engage


To reset your AC compressor, you need to remove power for at least 15 minutes. After you reconnect, the compressor should turn on. If it does, immediately turn to high and try to add refrigerant. Best of luck.
