Mazda CX-7 Problem Report
Mazda CX-7 Warm Air From AC System
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. - Visitor
