The engine may overheat due to erratic engine cooling fan operation as a result of a faulty cooling fan control module. Replacement of the fan control module would be necessary to correct this condition. Our technicians tell us the Mazda may provide assistance with the cost of this repair.

No a/c when Idling, Engine heats up. Fans come on for a few seconds, but not very fast, then quits. A/C works when your driving fast enough to get airflow across the condensor.

Leaking coolant and overheated, my car stalled during rush hr. It is not drivable because it would overheat and the engine would shut down. Steam was coming out of my hood. Fan was not working.

Fan continued to run for some time after engine shuts off. Fan comes on and winds up as soon as engine is started. During summer Air would not cool car. Dealer said the module had already been replaced twice and they would not replace it again. If they replaced it it was without my knowledge.

Car overheats when idle and ac won't blow cool. Car rides fine and air blows well when in motion. Only issue is when it is idle for several mins.

Fan continues to run after the ignition is turned off, repair shop said cooling system was okay, but for $85 they could connect it to the "computer" to tell me the same thing I just found out on the Internet, I will be calling Mazda to see what they have to say.

AC stops working when at stop light. Engine temp rises. When driving at speed AC will start working again and engine temp returns to normal.

Fans work sometimes. I replaced the module but did not correct the problem. Now 3 months later back to the same overheating problem but, now the fans do not run.

My fan has been spinning so fast you can hear it really loud I haven't been able to fix because of money.

Car overheated while in rush hour traffic in LA...smoke pouring out from under the hood, and temperature gauge completely up. Had it towed to my mechanic where he is quoting me $930 to replace the fan motor. Hopefully he can find used parts to save a bit of money. This happened 3 weeks after I needed to replace the transmission. I've only had this used car for 2 years, and it's only 5 years old. Needless to say, I may try to sell it as soon as the fan motor is repaired. I'm worried this may be a lemon with all these major issues. Does anyone know if Mazda helps outside of warranty? Thanks!

My Mazda 6 v6 2010 Model has this exact same problem. The dealership says they have to replace the entire fan assembly at a cost of $1,275 and that this is not covered under the 100,000 mile extended warranty on my certified pre-owned car.

Complete pain, two replacement modules and who knows if that will fix it. Either fans run the forever or never because of a drained battery.
