Finally, I could get my compressor to enrage but the problem still persists. I checked the low pressure port with a gauge and it keeps telling me I got no pressure left. First I pumped in 19oz super size of r134a. I got up to 28PSI. A day later, the compressor refused to operate so I checked the pressure again. Again, I got no pressures left and I pumped in another 19oz super size can of r134a. My compressor enrage and its pressure came back to 28PSI. Same situation happens a day later. My pressure was all gone and I pumped it with a 13oz r134a can. Seriously, today its pressure is back to 0PSI and I got no AC left. What amazed me most is I DON'T SEE a freaking leak ANYWHERE????????? What in the world is going on?????? Could my car be burning fluids? I used the more expensive brand, both 19oz and 13oz can, all 3 costed me $40 and still I can't get my AC to operate properly. I'd checked all of the lines tracing around compressor to condensor to the firewall and back and saw NO LEAKS???? Could it be a bad evap cooler???? Then again, I saw no leaks on my carpet either?? This is driving me crazy.

 

I took my car in for all AC needs...they have all the tools and know what they are doing(most of the time).....For like 50bucks you can have them service you ac system...check for leaks and they suck all the moisture out the system....

 

I didn't think you could "see" A/C leaks. My understanding is that the fluid evaporates as soon as it enters the atmosphere, because it isn't under pressure any more.

 

it's like trying to see air leaking out of an tire...you can't see it. use a dye and see where the leak is.
