You can pick up a can of recharge at your local auto parts store. Some states do not allow for the sale of this so don't be surprised if you find this is the case.

There are many options but the one you want has NO stop leak in it and will have a hose with a fitting already attached. Sometimes there will aslo be a gauge. The fitting will only fit on the low side fitting of the car. This fitting will be on the low pressure line which is the larger diameter of the to lines. I apologize for not knowing exactly where the fitting is.

With the car running attache the can of refrigerant to the low side fitting and open the valve on the can. Eventually the A/C compressor should start to click on and off. It will take a while for the can to empty once the compressor starts to work. You can tell when it is by shaking the can. You will feel the liquid moving around when it is full and no liquid moving when it is empty. When it is empty close the valve on the can and remove the recharge fitting from the low side fiting of the car. After the can is removed you can turn off the car. DO NOT TURN OFF THE CAR WITH THE CAN OF RECHARGE ATTACHED TO THE LOW SIDE FITTING!

Some Cadillacs require a scan tool to erase the low freon trouble code before the car will turn on the a/c compressor.

Switch interruptor


If we are talking about a pressure switch, it usually is the low pressure cut-off switch. Before messing with this switch, verify what your Freon pressure is.
If the pressure is low, the low pressure switch may be fine and you need to add Freon and find out why the Freon escaped.
If you have high pressure, there is a second switch which cuts power to the compressor. Too much Freon will activate this switch.
Tip: You have both a high and low pressure switch. The proper amount of Freon will center the pressure and keep the compressor running more consistently.
Either pressure switch unscrews from the fitting and with a minimum of pressure can be removed from the lines and replaced. The housing should have shapes for wrenches.

Toyota avalon A/C compressor cycles on and off to fast


Not sure what the question is - but you have to have the compressor running to add freon.
Most times if it is low you have to jumper the low pressure switch to make the compressor run long enough to add freon.
Under normal conditions, low pressure should be 35-45psi and high side should be 200-300psi with the compressor and cooling fan running.

My AC wont blow cold. As soon as I put freon in it, it blows cold for about an hour, then hot again. My friend told me that the orifice tube in his car needed to be replaced because it was convertine the...


Sounds like you might have a leak. If you charge the system and works for a time ,(hour, week, year) and then quits it sounds like perhaps the freon is leaking out somewhere. Freon does not ever get converted to air. Freon is in several states of existance while it is in your system. It is a high presure liquid, high presure gas, low presure liquid, and a low presure gas, but it is still always freon.
The valve your friend is talking about is called an expansion valve. What it does is to take the high presure "liquid" freon and allows it to pass into a low presure zone called an evaporator at a regulated rate. When you take freon at a liquid state high presure condition and expose it to a low presure environment it "evaporates" ( thus the name evaporator) and it gets very cold when it does this. This is where the cold air you feel coming out of the vents is made.
But the freon is in an enclosed system. By this, I mean it is never exposed to air, moisure (water), or anything else. I goes through all of these changes while inside this enclosed system.
Therefore, if the enclosed system is good then the amount of freon inside it will not change. If the amount of freon doesn't change then adding more will only make things worse.
I would suggest having the system checked with a hologen leak detector and/or system dye to find the leaks. Remember, if you have to add freon, then the freon that was there before must have escaped from somewhere.
Find a reputable shop to check the system for leaks. If it is leaking bad enough to run low in a hour it should be an easy to find leak.

The air conditioning compressor cycles continuously, sometimes cutting off the engine, and there is no longer cold air coming out.


Try to add freon,it is most likely low,and needs the recharge,also,if it leaked freon,it leaked oil,so put some oil in it also,If this was helpful,please rate,thank you.

I want to recharge the airconditioner, but the computer in the dash states refregerent to low compresser shut off! how do I turn on?


Add freon if not done yet, disconnect battery for 5mim, should reset, if it don't reset after disconnecting battery, your low pressure switch's are bad, that happens about 50% of the time when freon get's low. the low switch's are located on a very thin a/c line that run's along the top of the fire wall, there will be two about 12" to 18" apart, on the same a/c line, recover freon before removing switch's, install new one's evac a/c system and recharge with 2lbs of freon, hope this was very helpful.

Kia sedona a/c compressor is not engaging.check the fre.it is good.


If there is 12 volts at the compressor,then the coil on the clutch is bad.Most of the time,compressor with coil/clutch,is cheaper to purchase than just the clutch.I hope this helps you.

My ac blow out hot air and i want to put freon in my self and want to know how


Adding freon will not correct the problem. If you need to add freon, you have a leak, and you have moisture in the system, the leak should be located, mositure removed, then freon added. But to answer your question. Open the hood on, the left side you will see a round object called a dryer, you will see two pipes coming from it, one at the top and one at the bottom. The smaller is the high side, the larger is the low side. Obtain a can of freon either R-22 or 134a with an adapter for installing the freon. Turn the engine on, turn the AC to high. Add the freon to the ac using the low side.

Freon leak in line lincoln continental 97


use 134A and you can put it in your self.. Just pay attention Only instal freon in the low side of your system.. low side is always the larger hose ... Got that ? larger .. small hose is high side is not not the place to put it in .. Find your largest air conditioner hose and follow it out till you find a port to put in freon .. which you can buy it and the hose at a walmart store..they do make a sealant also that will sometimes slow the loss of freon.. let me know if you need more.. jerry
