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.Google+

Started blows warm air but other time blows cold air. Ended with smokes get out from machine compartment. Called mazda technician and he told it is from ac compressor. The solution is to change the compressor, but unfortunately there is no stock in my city. This almost 2 weeks and my car still stay in garage
Driving on the freeway when smoke started coming out from under the hood. Now, whenever i turn on the air, the whole car shakes.
