SOURCE: AC gets cool not cold, but has full freon

expansion valve setting probably needs adjusting for correct super heat setting.

SOURCE: How much freon does the 1994 Toyota camry hold?

The total amount of refrigerant in this system is 1.76 ounces.
It's hard to dispense an exact amount without a digital scale invloved. Good Luck.

SOURCE: My 2003 4 runner A/C runs hot on driver side and cold on other

I would doubt that the freon is the issue, if one side is cold. I would look at the air doors; look under the dash and see if the arm needs lubed up on the driver side of the air box.

I just fixed mine. My compressor clutch would not engage. The fuse under the dash checked as ok and the freon was fully charged. My compressor clutch wasn't froze, it just wouldn't come on. If this is the case for you, there is a fuse box under your hood, which contains an A/C relay switch. it is the first rectangular block to the left (looking towards your windshield). Mine was white in color. It's about 1" by 1/2" rectangular shape.
Autozone had this part in stock and it cost $27.99 . It was black in color...
Good luck!

SOURCE: AC light blinks and compressor will not run. Freon

Could be bad AC clutch relay. Just replaced mine ($11 at autozone). It is located in the relay box just behind the battery.

1994 ford mustang 3.8 liter a.c. compressor clutch will not stay engaged, blower fan works but not cold. freon is good

What is the pressure in your low pressure side at 80 degrees ambient? Did you use gauges?
U said the clutch will not stay engaged, meaning that it engages and then releases. If so, that means the clutch winding is good but that perhaps you have a loose wire feeding the clutch or a bad, intermittent relay. And if that is not the case then you are LOW in freon and the low pressure cut off switch is disconnecting the clutch when the pressure goes down. Pressure should be around 35 pounds on suction line at about 3000 rpm.

New ac compressor, not accepting freon, not engaging

IF this was a DIY job then I have to ask if you evacuated the system and or did you have isolation valves on the compressor? Are they open?
If you have the valves then you dont have to evac the system if it did not go all the way empty. Short of that are you putting freon in the high or low side? Did you bypass the low cutoff to see if the compressor is going to engage? Did you replace the oil? The receiver dryer?

How do you replace the compressor? Is there an online mannual? 2003

Physically changing the compressor is easy. Just two freon lines, a belt, one clutch wire, and a few bolts.
But first you need to capture the old freon, which needs a vacuum pump and tank.
It is technically illegal to just vent it, and it is dangerous because of the pressure and cold. (wear eye protection and gloves)
You also need to add the right amount of the right type of oil, depending on the type of freon (a 2003 should be R134a).
But instructions should come with the new compressor.
Then you need to add the correct amount of freon.
If you saved it, then you just put that back in.
Otherwise the instructions should tell you how much to add.

Diod you charge the a/c, if its low, by that I mean if it needs a charge the compressor has a cut out switch inline with the power wire going to the a/c compressor clutch(it can also be referred to as a fuse depending on who you arer speaking with), it is there to protect the compressor from burning out.
You see if the a/c system has a leak....any air conditioning system not just a car.... along with the freon leaking out a/c compressor oil can also leak out with it especially if its on the high side lines or the compressor front shaft seal(which is behind the a/c clutch). That is why it is equally important to buy a 1 pound can of freon + oil combo and a freon 1 pound can with leak dye combo in it, if its down a little in other words the compressor turns on but isn't real cold then only install the freon + leak dye as the leak dye will travel through the system and expose its colors when it appears at the site of the leak, giving you a visual on where the leak is.
try adding some freon to the "low" pressure side of the suction lines of the compressor(larger lines with a larger fill port, be certain to purchase the proper fill hose and attachment needed for your particular car.
The auto parts store will assist you in this proceedure.
You may have to locate the a/c compressor cut out I think its a threaded one that has a black electrical connector on top, remove the connector and jump the wires together to get the compressor to turn, then add the freon. Walla, the compressor is working and accepting the charge, if by jumping out the low pressure cut out switch no sound is even heard at the clutch you may have to replace the low switch as well.
This test also tells you if the a/c compressor and clutch are working properly, if you jump it out and it doesnt engage replace the clutch. You will need a puller, Auto Zone will lend you the tools for the job free if you buy the parts from them,cool aye?
Happy Motoring!!

2003 suzuki sx awd. during hot days 22 celsius, turn on a/c and loud rattling noise starts when car is at standstill at traffic lights. no rattling when on the move with a/c on. any good diagnostics will...

This hjas a possible two part problem, the first part is the a/c compressor has a clutch on the end of the shaft and is engaged with the a/c compressor switch turned on, which means while the car is running, you turn on the a/c and walla, you get cold air(as long as it is fully charged), the belt drives this clutch which in turn spins the inside of the compressor and starts to mechanically **** freon into it through means of the low(suction) side, the larger diameter port, once low pressure freon either 134a for everything built after 1994 or freon r12 for cars built before 1994 enters the compressor it is then compressed into a high pressure liquid which has a high pressure test port that is always smaller in diameter then the low side (fill) port.
When the clutch is engaged, it will only slightly rattle after it gets a few thousand miles on it however as the vehicle gets more useage and the a/c gets more useage(considered extreme condition useage) more use then normal vehicles would otherwise get, the clutch starts to wear out causing this rattle. A clutch head puller is used to remove the clutch can't do it without the proper tools, the belt must come off before doing the replacement.
Any parts store will have the tools and the clutch, you don't have to release any freon for this repair.
Another reason for a rattle could be the a/c system is low on freon and oil.
Buy a freon charge kit with a one pound can of 134a freon + oil combo and with the car running and a/c on high blow full cold attach the charge hose and freon into the low side port, rattle should cease soon as the vehicle reaches is full charge, should't take more then 2 pounds(cans) of freon, system hold 2 3/4 pounds empty each can is one pound.
Happy Motoring!!

When i turn on ac it blows hot air

Normally due to low freon. Also, notice if the a/c compressor clutch engages, as it will not if the freon is low.

Air condition is not cooling my honday civic lx 96? I bougth a freon's cane and hook it up but the freon doesn't get transfer into the car?what I am missing?

you need to put a pressure gauge on the freon input nozzle and see how much freon is already in your system You are probably getting no cooling because the clutch on the front of the A/C compressor is broken, or the switch on the dash is not opening the vents inside correctly. Putting more freon into an already full system can have unpleasant results. So if when checking the gauge, the freon levels are ok, next, run the car, and look at the front of the A/C compressor.see if the clutch clicks in and out as the A/C is turned on/off. If the clutch free-spins all the time it needs to be replaced, or if its silent completely, the wiring to the A/C needs to be checked. If the clutch is ok, head under the dash ad listen for the vent doors opening and closing as you cycle the A/C on/off. If you can't hear them, a vacuum pipe or electrical connection/A/C switch is to blame.

Air Conditioniong not working

U may be low in Freon gas.
When Freon is low there's low pressure switch that will prevent A/C compressor clutch from engaging to protect it from failure.
So, first check Freon pressure & any leaks form lines & hoses fittings.
Even if the fan is working, that doesn’t indicate proper compressor OP'S.
Look at the compressor front side you'll see the clutch stationary while the AFT pulley moving.

Then put air-condition compressor switch to ON (Engage),
You should see the clutch engage & start rotate,
If NOT, this is very clear indication u r low in Freon.

A/c compressor replaced but new one does not engage clutch

you need to jump the low freon switch to refill the system...this will turn on the clutch until you have freon in the system.

Air Conditioning

check the clutch switch plug"two wires on the compressor under the hood" it might have come loose, if not start car and turn a/c on, see if clutch is spinning, if it is not look on coolant switch, see if the plug is secure on it"round silver looking canister that a/c lines go to"if everything else checks out then probably low on freon. go to wal-mart get DIY freon kit, charge it like the little gage tells you. make sure you hook it to the low pressure side, bigger freon lines, small lines are the high pressure. you may have to put a jumper wire on evaporator canister plug"on the silver canister i mentioned before, to get compressor to take freon charge
