My Toyota's AC will be ice cold when you first crank the car up for the day and most of the time the air will stay cold until you cut off car . When you crank the car back up and turn on the ac again it will blow hot air ( once in a while it will blow cold when AC is cut on the 2nd time but not often ) I check the temperature of the AC and it runs around 35° to 37° . I have had it vacuum out and new Freon put in . Did not change anything . I did notice the gauges when the man had them on my car's AC . The low side show 0 the high side read around 2 or 3 hundred. One man wanted to put a new compressor and dryer on my car , but when I ask if this would fix it he didn't think it would . I live on fixed income and I can not afford to keep taken my car to AC people to look at it and not fixing it . No one don't know what is wrong with it . Can you help me please ?

You really need an AC expert to examine this car. It sounds like there could be a restriction, possibly the expansion valve but that needs to be determined in person. AC is a lot more complicated that most people think and it requires a lot of observation and experience.

Hi ,
The people I have been taking my car to were suppose to have been AC expert . They have been working on auto Air Conditioner for many years . One of them told me he has never came across a AC that would be cold when you first cut it on for the day and not stay cold . That is why I went online to try to find some help in finding the problem with my AC .
I would appreciate any and all help in finding the problem with my AC . I will have the expansion valve check . Is there a way I can check it ?

As I already stated, you need an AC expert to examine the car. Obviously this guy is NOT an AC expert. Many shops think they are but most are not. I am in South Florida and even here there are few true AC experts. It takes a lot of experience in refrigeration to analyze what the system is doing. This is not something ou are going to learn on the Internet
