Air conditioner evaporator vs. air conditioner compressor

(1999 Chevrolet Cavalier)
I recently took my car in and they checked it with dye and recharged it Charged me 73.00 2 days later it started blowing hot air and I took it back and again it was checked and told me it was the evaporator. Had it repaired but at the same time told me that it was the compressor and after paying 700 for the evaporator they wanted to replace compressor for an additional 500 dollars. Somehow this just doesn't make sense to me. Isn't the dye supposed to tell what the problem is? Anyway, after telling me they could put stop leak in it and that may or maynot work It just confuses me why a specific problem could not have been spotted with the dye or however they tell what the problem is. Have I been taken?

You are correct in questioning this repair. The dye is used to find small leaks in the A/C refrigerant system, that is all. It is rare that the dye will be used to condemn a compressor.
What was their explanation for wanting to replace the compressor?
If it's not too late, ask for the old evaporator, and in the future, always ask for the old parts. You may not want to take them home with you, but at least have them show where the defect is. In this case, you should have seen some oily residue and dye where the leak was coming from.

I'm suspicious of why the evaporator was replaced. It is possible that there are no signs of leakage if it has a very small leak, but a small leak was not the problem. My feeling is you paid for a repair that was not needed, or it was not the main cause of your complaint. You would have to have the evaporator tested to know for sure if it is leaking.
I would talk to the service manager, or owner of the shop, tell them what the situation is, and that you may have had to pay for an improperly diagnosed problem and see if they are willing to work with you. If not, then I would take it somewhere else.

I did get the evaporator back and nothing visible like oil or anything so he says that when he changed the evaporator he let it run and then the compressor started to leak. I am so totally confused. I questioned about spending 700 for a ten year old car but decided i wanted air and now this with the compressor. He says my 700 was to pull the dash and that was a big job. I know that and just don't know what to do next at this point. He does want to charge me 537 for a compressor (includes labor) This auto repair was recommended by plaza tire that is why I went there otherwise I knew nothing about this place and yes I am a female unsure what to do next I am by no means a wealthy woman and can't afford no more money any suggestions?
