The cooling fan module can fail causing the fan to either run constantly, or not operate at all. If the fan runs continuously, the engine may not warm up properly, and if the fan does not run, the engine may overheat. Mazda has a voluntary recall on model years 2002-2003 to address this concern.

Mazda MPV Failed Cooling Fan Module May Cause Fan to Run Constantly or Not At All
Mazda MPV Problem
Average Mileage: 105,109 mi (42,300 mi - 184,000 mi)
The fan continues to run even after the car is shut off and all the while it is running. This has drained the battery on many occasions. I figured out a trick to get it to shut off though. When turning the ignition off, if it stays running, just flick the ignition back on, but no so far as to start the car, and then back off. This usually does the trick. There is a recall I found, http://www.mpvclub.com/recalls.php?id=16 that may apply to your vehicle. Don't take no for an answer from your local Mazda dealer/repair center. This is a defect and should be taken care of by them.

Cooling fan stays on as soon as I start the engine and sounds very loud. I've seen a recall for this on Mazda MPV 2000-03, but not for my 2006 and it's the same problem!! Dealer said it's going to cost me $300 to fix.. They should have fixed this issue already if every year since 2000 been having the same problem!!!

Fan ran constantly; local mechanic fixed fairly easily (approx. $130 as I recall)
I get this PID code once in a while.

Fan runs from the turn of the key at erratic sppeds, mostly high, right until i shut the car. Car at the time has no a/c on or is in danger of overheating

The recall problem was supposedly fixed on this car in 2004 but the fan runs all the time again and even after the engine is turned off. I too discovered that if I turned the key on again and then back off again without starting the car, the fan stops but it starts right back up when I start the car again. The dealer said, since it was fixed in 2004 that their responsibility has ended...even though the problem is back again in full force.
