Look for the thick pipes vs. the thin pipes and a quick connector that goes on to the hose that fills the r134a via a can of freon.

Or, do you mean, where is the freon leaking out of? The freon leaks out of o-rings, seals, and possibly the compressor.

I had a compressor changed in my 1990 Cadillac Deville because it was leaking there. This is a common problem on older cars.

Good luck.

SOURCE: air conditioning won't work on 2000 subaru outback

the most common cause of course is a low system refrigerent charge, this would be due to a leak, the most common cause of leakage is the front shaft seal of the AC compressor

On that model,it will cycle on and off while you add freon.If it does not ,then the ac system might have a problem.The low side pressure switch is located on,or near the accumulator .Unplug the switch and take the wire end plug and connect the two plug in`s together(cross it out on the wire).This will make the ac compressor engage and you can charge the system,do not leave the wire connected,plug it back up to switch.If the ac compressor does not come on ,then have the system checked out.

The "O" rings could be bad thus allowing all the new freon to leak out again. This happened to us.

SOURCE: air condition blows hot air but it has freon

You may have created an over charged condition and at this point the a/c compressor will cut off on high head pressures. This can be verified by installing gauges to the systems high and low side service taps and reading the pressures.An overcharged system will start the compressor briefly but soon cuts off once pressure goes to 350 - 400 lbs on the high side. Acceptable pressures for this system should be no greater than 250 high and low suction should drop to 40-50 psi.You might recover the charge and evacuate the system,then try bringing the charge back to proper level.A sight glass in the reciever drier really helps determining proper fill.Once all bubbles have dissipated from the sight glass during charging ,one should stop at that point to avoid overfilling.Too much freon is worse than a low charge especially in hot ambient conditions....

SOURCE: Recharge freon. How do you add freon to the air conditioning?

when the ac doesnt blow cold and the compressor pump doesnt click on ,this can only be done with the proper machine to remove the gas and weigh how much was taken out ,then oil recovery and a vacumn then recharge with the corerect weight of gas .

Diagram on how to install freon for air conditioning


freon is added though the suction side service port. if you don't have a manifold gauge set to check system pressures first then you might be doing more harm than good. if you took the system apart for any component change, then you will need to replace the drier/reciever and evacuate the system using a vacum pump before adding freon.

Air conditioning not too cold ??


Hello,
google_protectAndRun("ads_core.google_render_ad", google_handleError, google_render_ad); google_protectAndRun("ads_core.google_render_ad", google_handleError, google_render_ad);
Let me explain in layman's terms how the air conditioning (AC) system works and what could be happening to your car.

Like your body, the air conditioning compressor is the heart of the AC system, and Freon is the blood. The compressor pumps Freon throughout the AC system, either the older type R12 which costs as much as gold it seems these days, or the new environmentally-friendly R134A Freon. This Freon is a gas and liquid combination that is compressed and circulated throughout the air conditioning system. The compressed Freon is pushed through the system under pressure and is passed through different sized metal and rubber hoses and a special valve called an expansion valve that cause the gas to expand and contract.

This expansion and contraction makes the Freon gas very cold. This cold gas makes its way via metal lines into the dash area of your vehicle to the evaporator core. This evaporator core is like a small radiator, except it has cold Freon circulating inside and not hot antifreeze. A small fan (the AC blower fan which you control from the control panel on the dash) sits in front of the evaporator core and blows air across this cold evaporator and then through the vents inside your vehicle.

The other objective of the air conditioning system is to remove the heat from inside the cab of the vehicle. This heat is removed by the Freon with the help of the AC condenser located at the front of the car (usually in front of the radiator). The Freon coming back from the evaporator carries the heat from the cab to the condenser via rubber and metal hoses. Just like your radiator, the condenser is lightweight aluminum with many internal winding coils.
The Freon travels through these coils, and in between these coils are small slits or fins that the Freon is forced through. The condenser will have an electric cooling fan mounted in front or behind it to push or pull air through these fins to remove the heat from the Freon. Some vehicles still use the old fashioned fan blade driven by the engine to pull air across the radiator and the condenser.
Now I know that is just a tidbit of information on how the air conditioning system works, and it is very general, but I wanted you to know what to look for to give you insight as to what might be happening with your vehicle.
A few causes of low cooling efficiency or no cooling at all at idle are:

Lack of air flow across the condenser. Make sure the electric cooling fan motor near the condenser is coming on, or in models that are equipped with a fan blade make sure this fan is turning and is turning very fast.

Low Freon levels. Freon level and pressure should be checked by your certified air conditioning mechanic.

Overheating. If the engine is running hot or overheating, it can have a noticeable negative affect on the air conditioning system. Some cars have two electric cooling fans, one for the air conditioning condenser and the other for the radiator. Make sure they are both working properly. Usually at idle on a hot day with the AC on both fans will be on.

When the vehicle is traveling at freeway speeds, the compressor is pumping the Freon throughout the system much faster and harder than at idle. There is a dramatic increase in air flow across the condenser due to 55 mph winds, and the engine is usually operating at a cooler, more efficient temperature as well, thus allowing the air conditioning system to operate efficiently.
Note: An air conditioning system that is somewhat low on Freon can still feel comfortable at freeway speeds due to the added air flow across the condenser which can overcome the ill effects of slightly low Freon. Periodic air conditioning performance checks by your mechanic are the best way to keep the system in great shape.

Hope this helps.

Goodluck

My air condition want' blow out cold air i try


If your car is more than a few years old, it probably has a leak or a worn compressor. You can add too much freon for the system. It needs to be vacuumed down to a negative pressure before adding freon, and then checked for compressor function and leaks. You may need to take it in to a reputable shop.

Air conditioning failure above 85 degrees.


Initially I would suggest a Loss of FREON from the system, but there are also several reasons for the A/c to quit. Freon loss,[Leaking seal, Comp. front shaft seal, Split hose, Holed Condenser, Compressor Realay/Fuse failure, Thermo couple switch].
An easy out, is to Purchase 1 can of Freon with added Lubricant and 1 Can of Pure freon.
Inject the 1 Can with Lube into the High Pressure Side Adaptor Port. Look and Listen for Leaks. Start up, with Blowers on FULL speed, A/c Control on Max. A/c, and Heater Coolant Control on Cold[Blue]
Speed up the Engine to about 1500 RPM. Look to see if the Compressor Clutch on the Front is Engaged and Rotating, if it does wait about 30 seconds, and the Condenser Fan should Engage, continue to run the engine and check the Interior of the Vehicle for a change in AIR flow temperature. If it is cool, but not cooler. Stop the engine, and give about 2-3 minutes before adding more Freon from can 2.
If none of this happens to make it work, then I suggest you go to a Reputable A/c Repairer and ask for a CHECK & ADVISE ONLY,on your vehicle, so as to get an ESTIMATE, for repair of what is apparently defective in the system.
Regards,DT
