Warm Air From AC System on Mazda CX-7

Problem Description and Possible Solution

The AC compressor may fail causing the AC system to blow warm air, smoke may also appear from the engine. A failed AC compressor will require replacement. Mazda has extended the warranty on these compressors to 5 year or 60K mikes. If these conditions are noted our technicians recommend to turn the AC system off and have it inspected as soon as possible.

Ac blows very cold and then it stops for several days and start again blowing very cold. What can it be?
It blows cold some times and some times it dont.
compessor locked up and it started smoking like burning rubber.
A/c just stopped working and blowing warm air!!
Ac blow warm air. It makes a loud raddling noise from under the hood of the car when on.
Same thing happened in 2010. Now it's happened again in 2015 and Mazda is not covering it. Warranty lasts 12k or 12 months. Just prepare to buy a compressor every 4-5 years or sell it. PCM recall in 2014 after changing out in 2011. And now EGR needs replacing only months after. I'm done with Mazda vehicles.
made alot of noise and it got worse
it began to start blowing warm air slowly. In the next day it went to not blowing any cold air no matter how high i set the fan.
My air stared blowing hot air , year before it was blowing hot air . Mazda in Lake Charles, LA fixe the air . about 10 days ago it was blowing cold air , after I stopped the car for about 1 hr it was blowing hot air . Mazda inLake Charles want $745 for new compressor , but my warranty expired .
Ac compressor failed
Smoke from under hood while driving on freeway
Keep loosing refrigerant even with sealers. Mazda wanted 1200$CA. Not done repairs so far.
Driving on the freeway when smoke started coming out from under the hood. Now, whenever i turn on the air, the whole car shakes.
It blows cold air out while the car is moving, but if you stop at a red light or stop sign it blows out warm air
AC blows warm air and cold air is intermittent
Bought car used from a dealership with a written agreement that the a/c be fixed. Took ownership of the car the a/c worked for about 2 hours then there was a brief burning smell. Took back to the dealership they found a leak and fixed it. They had previously replaced the evaporator coil. Now when I started the vehicle there was a strong chemical smell and a noise behind my glove box. The air only worked first thing in the morning. Took it back to the dealership they replaced the compressor. Got the car back the air doesn't work. Took it back to the dealership. They're at a loss.....
My car has not been fixed, the a/c which had always been great just suddenly stopped blowing out cold air due to a failed compressor. I have been quoted over $1000 dollars to fix a problem which was caused by a defective compressor and should be mazdas responsibility to fix. In 96 degree weather, and having multiple sclerosis which symptoms are triggered by heat, this is a true health hazard for me!!
not engageing at all . had it checked to confirm compressor broken
Heard noise from under the hood got a stinky smell from the engine compartment smoke it did quit after a short period of time but the compressor clutch looks to be fried
they was smoke coming from the engine, and i turned the ac off, and since then theres no smoke
