SOURCE: a/c not working blows hot air add 134a need help 99 f150 4.2 v6

Before you add freon to measure how much freon is clucht checks if the compressor is activated when you connect the air conditioner if the clucht not activated and have a good pressure in the system looks at low pressure switch that goes in the drier and that very often these are damaged, you also have to check the fuse and relay the compresor.Thanks

2003 ford focus no cool air is blowing out. Could it be the evaporation cord?


Make sure your blower fan is turned on and is blowing air. When you push your a/c button the yellow light should come on. If it is not blowing cool, it could be several things. Low on 134a or the control that has the a/c button on it could be bad or blown fuse, bad compressor, etc. If the air is cool but not cold the 134A is low. If it is still blowing hot, check and make sure that the clutch on the compressor is locked in. It most likely is not. Check ac fuses and ac relay, if they are good, check the 134a ,if low, refill it. This should fix it. Remember that if the a/c clutch is not locking in, you cannot add 134a because of no circulation.On some vehicles, if it is completely out of 134a, the relay will not trip and you will have to bypass the relay to provide power to the compressor to fill it. If you do all of these and it still does not work, you will need to take it to a professional. If you need to, reply back and I will give you more possibilities.(I think that you mean evaporator coil)

AC come on but will not cool freon has been checked and some added but still will not cool and it is hot here in IRAQ.


well if your not HVAC certified, you have what is know as Synthetic freon and your not gonna be able to buy the real R-134a, also if your car is made b4 93 your not gonna be able to refill your freon with out a conversion kit. they don't sell the real R-134a because its a dangerous pollutant and you need to have an HVAC certification to buy it. Now if you had it professionally refilled and it will not cool, then your compressor or condensor needs to be serviced by a tech. They are extreamly delicate parts that must be serviced by a qualified ASE technicain

A/C unit blowing hot air when selected to cool on


Your A/C unit is low on Freon, or you have a bad pressure switch. Turn on the Air Conditioner, with the engine running, & put it on Max. Open the hood, & see if the compressor is spinning. If it is not, then you need gas. You can buy refill kits at a local Walmart. If you have a leak, it may be a wasted $30. That is what I paid for a 22 oz. can of R-134A Freon. I had a dealer regas mine & put in a dye that they can find leaks with a black light. It may be cheaper in the long run. My drier, in front of the radiator has a leak. It will cost $460. to replace it.

The ac in my moms car is blowing out air but it comes out hot. dose that mean it needs freon? if so where can i buy some?


The bigger question is how did it lose the Freon to begin with. You can get R-134a at most parts stores and the fitting on the refill cans will only fit on the low side but if you don't fix the leak it will just go low again. try auto Zone for a refill or booster can if you are looking for that.

The air conditioner blows hot air. Is there a way I can test for a leak in the system or does this require a technician? I am thinking it's not a compressor because it is blowing.


Apart from doing a low side pressure check, you can try to recharge the system yourself with a refill kit that's readily available at most auto parts stores. If you're concerned about a leak, also get a can of R-134A with the UV dye that will show any leaking components.
RECHARGING AC SYSTEM


  1. Turn the truck on and turn AC on HIGH
  2. Locate the low side AC line (will have a valve and cap similar to the cap on a tire)
  3. Insert the oil or R-134A can to the hose (Do not turn the screw to puncture the can yet)
  4. Insert the other end of the refill hose to the low side valve
  5. Puncture the R-134A can with the screw on the refill hose
  6. You should feel the system suction the refrigerant out of the can
  7. Check for frost on the AC lines and the air blowing inside the truck
  8. If frost develops and the air is cold, you've successfully recharged the system and disconnect the refill hose. DO NOT ADD MORE REFRIGERANT...overcharging the system will damage your compressor and will be less effective
Hopefully this answers your question and you're able to get your AC working again. Best of luck.

The ac only blows warm air, have recharged it with freon but it only cools minutes before blowing warm again, could find no leaks


There are special cans of R-134A with dye in them for detecting leaks. Most leaks occur around the fittings near the compressor. Recharge the system with the leak detector can or R-134A. There are also cans of R-134A with an additive to stop leaks. I would use these products to either detect your leak or to stop it. Best of luck.
