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.

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.
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.
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 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 .
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
Driving on the freeway when smoke started coming out from under the hood. Now, whenever i turn on the air, the whole car shakes.
AC stopped working, we could hear a hissing noise from under the hood; the car runs fine otherwise. We have not gotten it fixed yet.
A/C stopped blowing cold air. Started intermittently and after dealer fixed the detected problem, the compressor went out a week later during a road trip to Montana in 100+ degree weather!
