Needs to be checked for a freon leak, best way to do this is to recharge and add dye, with a uv light you will be able to fine the leak, most auto parts sell the dye, and the flash light you will need to fine the leak, good luck.

Ac not cold cool but not cold


Have you recently added R-19 refrigerant to your Jeep? The 1989 model base requires R-19 Freon, not the newer R-134A designed for the newer cars...Has your stock system been re-fitted for the new R-134A refrigerant? If cool but not cold, the system could be low...or need a clean/new orifice tube...Try for a free inspection in your area...

On my 2006 ac works good when engine is cool, in stop & go traffic it blows hot air & head pressure gets high in ac, car temp is ok what's wrong


How do you know head pressure is high? Do you have an auxiliary electric cooling fan that is not coming on in this situation? It should be in front of the AC condensing coil. There may be a switch tied to the system that is bad. This switch is sometimes activated by the pressure in the high-pressure line to the condenser coil. If there is not enough freon (134a) the pressure will not be high enough to activate the cooling fan switch. I recently added one can to my system and it made the fan run whereas it did not before adding the freon.

97 Plymouth Breeze won't blow cold air due to freon leak.


Your AC system is a closed system, so the fact you have to put more Freon in, means there is definitely a leak. I would check it out with a mechanic.

2001 hyundai santa fe air conditioner not blowing cold Have added a/c stop leak, added freon, added antifreeze.


The problem with what you have done is to introduce faults into the ac system. The ac may have stopped working from over or under pressure in the system in which case the ac compressor would stop working. There is a very fine tube in the evaporator that is easily blocked and will not allow the gas to pass from liquid to gas and so cool the car. I suppose you checked for power to the compressor clutch before you touched anything as it may be a faulty ac switch or fuse.. If you put antifreeze in the ac system then you are up for a complete system as the glycol will destroy all the internals

Ac not cooling blows colder when driving and not much at idle added freon same problem,after adding freon check engine light came on?


RCV Valve is causing this issue. Refrigerant Control Valve. $40.00 part but most mechanics will want to replace your compressor.

Have a 1992 toyota corolla. I put a can of freon in it for my a/c. It got cold for 2 days and then only just blow out cool air. What can be the problem?


air conditioning sytems are assembled with o rings at each connection to seal the system, as these dry rot and crack over time, they fail and cause leaks in the system. you added freon , but then it leaked out slowly over the next few days. a garage can inject colored dye into your ac sytem and find your leak, but it will cost you.

AC SOMETIMES COOLS


It is possible that the AC compressor clutch cycling is getting stuck in the off mode, this can be caused by a sticking expansion valve or a defective AC clutch control relay. One note u said u added more refrigerant to the system, if u over charged it you may cause damage to the compressor a $400 part and equal labor to replace, it might be a good idea to have the system charge checked by a shop that does AC work.
