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.

compessor locked up and it started smoking like burning rubber.
Ac blows very cold and then it stops for several days and start again blowing very cold. What can it be?

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.

A/C Compressor kicks on and off when A/C is on max. During hot weather outside, 90 degrees or higher temperature, the cool air seems to stop flowing during driving and non-cold (regular - not hot) air comes out. During nighttime, when temperature drops, A/C seems to blow colder air. Added Freon to about 45 PSI using the gauge that came with the Freon. Prior to adding Freon, PSI was about 25 PSI. The same issue is occurring after adding Freon. When I have the hood open and the A/C is set to Max while engine is on, the A/C compressor does turn on and off. It turns on for 3 - 5 seconds before it turns off for 3 - 5 seconds. The pattern becomes repetitive. It seems like the A/C compressor is not staying on long enough to actually push out cold air inside the vehicle.

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.
600 to fix!!
AC compressor had to be replaced...thermostat replaced...check engine light came on, rpm started going crazy from 1000 to 3000 rpm while accelerating, car was losing power, thankfully able to turn into a repair shop. believe it's the turbocharger.

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

AC blowing warm air. Dealership replaced compressor under warranty
A lack of power may develop due to a failed turbocharger. Failed turbochargers will require rep...
Water has been leaking I to the front passenger floorboard. I think it is the air conditioner...
Need ounce amount and PAC type.
2008 cx7 started to blow warm air yesterday. No weird noise. Compressor or rf134a needs filled?...
