Try disconnecting battery for two minutes to reset the system. Then start the car and check a/c operation.

AFTER REPLACED THE HEATER CORE AND THE VALVE TEMPERATURE CONTROL NOW I CAN'T CHARGE FREON ,HOSE FREEZE AND IS NOT CHARGING


The water system and the Freon system are two different things. You would just use antifreeze in the heater core and control valves for this system.

The Freon system should have remained sealed unless it was disconnected to move it out of the way. It is usually recommended to replace the dryer (black oblong tank) whenever you open the Freon system. If the Freon system was opened, you need to borrow a Vacuum Evacuator pump from an Autoparts store and run it to pull out all the air inside the lines and create a Vacuum for the Freon to be added.

There are special pliers and "O" rings for the joint unions.

Next, for the Freon system, you would need to jump the low pressure connector switch to activate the compressor clutch to draw in the Freon. It is going to take several cans of Freon to recharge an empty system. Not all cans are the same size, and I recommend 1 can having at least some oil charge be added to the fill. Like car sizes, each car has different amounts of room for the A/C equipment lines. The Manufactuer should have a label stuck around the fan shroud to show how many ounces the system will take. More is not better. You will get into partial can situations, but Freon can stay in the dispenser can if you have good equipment to leave attached.

You use pressure gauges which can also be borrowed from Autozone, for instance, and used to measure the amount of Freon you have installed. Once you have put in 1 can of Freon, you may be able to reconnect and remove the jumper wire from the low pressure harness. The A/C compressor clutch should continue to cycle and draw in Freon when it does cycle.

Overcharging the system will break hoses and may damage seals. There is a high pressure cut-off switch. So you want to charge the system to have pressure between the low and high pressure cut-offs to work at optimum efficiency.

I hope my solution helps you.

My air conditioner works but does not cool . i have added freon the last two years and fixed the problem ,did the same thing this year but did not help .


When self adding freon after it leaks out you get air trapped in the system. After adding freon a couple of times the air expands not leaving room for the needed freon. To continue adding freon with air tapped will knock the compressor out pretty quickly, there's not enough room for both & the air is keeping the freon from being able to cool properly give the false indication of being low on freon. The freon you are adding has the dye added to assist in finding the leak since freon does not evaporate nor dissipate it its being leaked out. A black light will assist locating the leak. The best thing is to have the unit checked & serviced by a mechanic...he'll charge about $ 150.00 to check for leaks, remove the old freon...his machine will tell him how much air its trapped in the system by how little freon is removed. For the service fee he will replace valves & gaskets, where needed, correcting most leaks. After sucking the system down & recharging the problem should be corrected.

Where do i ad freon to my chevy equinox


You shouldn't ever have to add freon to an a/c system. It is a closed system - like your refrigerator. When was the last time you added freon to your refrigerator or home a/c when there wasn't a problem?

If you are needing to add freon, then you have a leak somewhere that needs to be repaired. Your local automotive technician can diagnose the problem for you. Freon should only be added by trained professionals. If you don't know what you are doing, you can charge the system incorrectly causing significant damage to the system.

If you still want to do it yourself, reference this article.
You will need a set of A/C Gauges, and freon.
Do NOT put any type of stop leak into the system - this can cause irreversible damage to the compressor.

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.

How do i put freon in my 1988 chevy s10?


Just start the engine and run your a/c. connect the hose (this hose is probably one you bought at the auto parts store along with your freon.) Relese the freon by screwing the object that is attached to the top of your freon can in and then out. Let the freon completely **** into system. You will know when your system is at the opporating level when your compressor stops clicking on and off and stays on. Most systems take only two 16 ounce cans of freon to be charged.

How can i recharge the air conditioner? Where is the hose located?


Ok if you want to do a home repair in hopes of saving yourself a lot of money and with hopes your system is not in major trouble, here goes:
First step buy 3 types of 1 lb. cans of refrigerant R134a at a parts store, 1 can of leak detector freon combination, and if possible 1 can freon/air conditioning oil combination freon along with 1 can of straight r134a freon.
The store will sell you a charge hose with a cheap type of charge gauge attachment and fittings to attach to your system for the re-charge.
Providing your system is low on freon,First, with the vehicle running and the a/c on full cold, high fan, install the 1 lb. can of freon/oil combo first only charging through the low pressure side of the system never through the thin line high pressure side as the pressure from the high side can enter the cgharging freon can and explode it like a bomb,(this low side line is the larger hose and the low side charging hose fitting the parts store sells you will only screw onto the low side charge valve which is normally marked "low" on the top of the plastic dust cap that is factory installed(hand screwed) on the low side valve fitting.
Secondly after the oil/combo can is emptied into the low side and you of course are wearing mechanics hand protection gloves and eye protection googles, then and only then will you install the leak dector 1 lb. freon can combo.
Third you will install the last 1 lb can of r134a freon, however your vehicle will not allow the whole last pound of freon into its system by means of a pressure relief blow valve that will automatically blow off any excess pressure once the system over fills, the system typically holds approximately 2.75 lbs. of freon.
If you have successfully installed the above freon into the system it should be up and running providing the system is in fairly good working order, by that I mean it may have a very slow leak that allowed the freon tio originally escape in the first place causing you to refill it, and if it does have a leak the leak detector die that you installed into the system should leak out from wherever it may be escaping from, indicating the place of needed repair by means of a red or blue, or whatever other designated coloration the die gives out from the leaking area.
Please note: Not all home charging techniques typically work as there are many mechanical failure factors in an a/c system that may require a certified a/c technician to determine exactly why your system is not working should the home remedy fail.
I hope this helps you and remember to always work safe with eye and hand protection especially around freon gases which become extremely cold and can cause frost bite when contacting with the bare skin.

Massage said low ref ac off what dose that mean thanks


that means low refrigerant available and the low pressure switch is preventing the compressor from damaging itself. You will need freon added to the system which in not uncommon since mobile a/c systems normally leak a small amount each year and eventually need topped off to work properly. Either buy some freon from a parts store or find an independant repair shop that will agree to just add the freon necessay to make the system work again. Freon necessary on most systems ranges from 1 to 2 pounds and freon bought in bulk by all shops costs $3 a pound and labor to do this is about a half hour so look at their labor rate and add a reasonable profit for the freon and this is what it should cost. If this helps please reply cause that helps me and good luck

I can not install freon in to the system. what


Could be your hooked to the wrong port.

Could be the system is full...what makes you theink you need refrigerant?

By the way FREON(R-12), is no longer used...your system probably takes a refrigerant called R-134a.

You may have a blocked orrifice tube or expansion valve.
