A/c blowing hot air
Answer
did you hear the compressor cycling on and off, Im not sure but I think that has a expansion valve instead of a orfice if the valve hangs you will not get cold air, if the compressor was cycling on and off that means its usually low on freon or you have a clog some where in your system causing too high head pressure....
You have all of the symptons of a leaking air conditioning system. Look on the list of things the mechanic did, and see if one of the items is a leak check of the system. If so, what kind of warrenty did he offer? I would first take it back to him and see if he will make good on any promises he may have made. If he suspected leaks, he should have put some dye in the system. Now he should be able to look and see where the leak is, and hopefully it will be something easy.
I have to warn you, that if that is the original compressor, it may be ready to be changed. They usually will run around $500 or more to replace, and the accumulator and orifice tube will have to be replaced also.
If by some chance it is not leaking, then he should be able to fix your problem. I know this is costing a lot of money, and if your climate is where you can do without a/c, then just run the air on vent with the windows down. If you can make it another month, things will start to cool down, and give yourself all winter to save some cash for repairs.
Thanks guys. I,ve been told by my brother who is a retired mechanic, that its probably the expansion valve. I just hate to get that replaced and find out that wasn,t the problem. I got a good deal on this car$1200.00(cheap), and I hate to put alot of money into it. I live on a fixed income, so its hard for me to play musical parts replacement. Thanks again .
