AC blowing warm after dealer replaced compressor 1 year and 1 month ago.

So the a/c worked good before the compressor locked up?Also it worked good after the compressor was replaced?Heres what you have to understand about your a/c system its the most fragile and one of the most expensive parts of your car.

Also a leak can happen at anytime or a small leak can get bigger at anytime. Also a hose can leak blow etc at anytime you have a expansion valve fail amd cause the pressures to make the a/c not blow cold. There are more variables on the a/c system in your car then any other part of your car I think.I always put dye in the a/c system when charging it or making repairs incase of leaks or future leaks. If they didnt do that it doesnt mean that they are at fault or did something wrong. Alot of things could have happened to the a/c or failed since the compressor was replaced doesnt mean they cheated you or did something wrong. To assume they did something without having it looked at to see what happened is wrong. Thats my take on your a/c and a/c in general.

From my experince of working on a/c I have come across leaks that showed no signs of oil leakage bit was still leaking charge.I have also had a/c leaks that were hard to find with dye the dye wasnt leaking out but there was still a leak. Those were on a/c condensors leaking at the top of them so the dye was settling lower and not leaking out. Again in my expernice without hooking up gauges to read high and low pressures adding dye checking charge levels etc I cant tell whats wrong with the a/c system. Again sorry if I insulted you that was not my intention at all.I cannot assume someones skill level on working cars that I have never met or talked to. Most of the users that ask questions on here arent really knowledable about cars. But are users that ask questions on here range from single moms diyers repair shops etc.

To tell how charge is in your system now you would have to recover it with a a/c machine and the machine would weigh it. It goes by weight not pressure. Those gauges you get from the parts store may say when the a/C is full but thats not a accurate weigh to know how much charge is in the system. Also the low side will read high until the a/c compressor comes on then it will drop. You also have to check the high and low pressures with the a/c compressor running. One gauge will only tell half the story.

I know Gm dealers have a 12 month 12,000 mile warranty on all repairs and some items are longer. Not sure about chrysler cars though I only worked at gm dealer.

Wow thats crazy the a/c compressor will cycle off if the engine coolant temp gets too high. The reason being is because the ac pressures get too high and the a/c pressure switch cycles the ac compressor off. But you should have seen the higher temp of the coolant on the temp guage. But glad to hear you got it fixed.
