I have a 2003 MPV with the same problem. There was a recall in 2004 to replace the fan controller module, which apparently would fail regularly. I had mine replaced under the recall although there were no symptoms at the time. Now it appear that the replacement has failed, but I've already used the recall and you can only do it once. Even though your warranty is up the recall still applies if your car is of the model that qualifies. Call your dealer, and he can tell you if you are eligible. It is almost certainly the problem. I don't care how you drive or what the temperature is, your fan shouldn't run immediately after starting or run for more than a couple of minutes after you shut it off.
I had the same problem as above. Went to dealer bought a $30 fan control module and problem is fixed. took about 15-20 min to install and only a 10mm socked or a phillips screwdriver. either will work.
This is most certainly caused by the Fan control module. I have one on my desk right now, staged to go into my 2004 MPV ES with 86000 miles. The Mazda recall campaign only covers up to 2003 models. This R
I am hearing 2 different problems. If your fan keeps running a couple of minutes after turning engine off , this is normal. It continues to run until the temp sensor reads below a certain temp. I am also hearing some fans that start running as soon as the engine is sarted ( before it has warmed up ) I have also seen fans that fluctuate speed and/or run a long time after engine shut down. This is a faulty Fan Control Module
A lot of times this will happen as the fans are not linked to the ignition switch at all. This is simply cooling the engine down with air. There's a thermal switch that tells the fans to turn on when the water reaches a certain temperature. At this temperature; the fans will engage causing an increase in cooling on your coolant system.
A lot of times this is just simply because of the weather, however, many other factors could be causing this problem. Overheating is a serious problem and should be dealt with quickly. However, usually this is just a sign of hotter temperatures.
This list is a possible set of variables you could be getting this from.
- Ambient (outside) temperature to high for cooling to effectively cool the engine while running
- Low oil causing increased friction within the engine.
- Old cooling fluid cannot provide adequate cooling
- Restricted radiator not allowing enough airflow to keep cooling system working properly
- Low cooling fluid or leak of some sort
- Overloaded vehicle (too much weight causing excessive stress on the engine)
- Binding transmission or brakes somewhere causing excessive stress on the engine
- Excessive throttle usage (driving it like a race car)
Those are some things that will make the engine run hot. It's most likely not running too hot for the engine, but however the cooling system just isn't able to control it to the point where the thermal switch turns the fans off and you must let it sit until they do switch off. As I said before, you most likely have no control over the fans unless you rewire them without the thermal switch engaging and disengaging them which I do not recommend doing.
This is normal they are computer controled and will run to cool the engine to the parameters set. when you turn the key you are just reinitializing the system hence why they shut off . they will shut off on their own without draining the battery or have any adverse effects to the vehicle. please rate this.....thanks
I had the same problem with my Mazda 2003 MPV. The fan module had to be replaced. The part is about $80, and labor is twice as much.
I replaced the fan control module that fixed my problem fan runs normal i found the part on ebay for $55.00 replaced it myself fairly easy

I have the same problem as troyhigdon's, except that in addition, my fans will sometimes come on as soon as I start the car, or else go on and off while I'm driving. Mine is a 2003. I know someone else with the same problem. Neither one of us drive it like a race car, and the register on the dash always shows the temperature of the engine to be right in the middle. It started soon after the 4 year warranty expired (of course), about a year and a half ago. My Sears Die-Hard battery did drain a year ahead of time...What diagnostics should be done to be sure nothing's burning up in the engine? Thanks for your thoughts...
I have an 01 MPV and have begun having these and other problems in the last year to year and a half. Most of the time after Ive gotten home and gotten two kids out of car seats and their accumulated stuff and gotten into the house the fan is still running. It turns on as soon as I start the vehicle and usually continues the whole time its in use. I too had to replace a battery that passed before its time. I have had to replace the water pump,the lines for the rear heater coil, had the entire system power flushed when heat then stopped working, had numerous occasions for engine light problems...I could really keep going....ALSO is anyone sure the trans isnt going to last long?

My fan runs at unusual times, like with the engine cold, and right after you start it. There is no way this should be normal. I think it has something to do with a bad sensor or relay in the cooling fan system. 2005 MPV.
I have a 2004 Mazda MPV, and I have just noticed the fan under the hood is running alot and staying on after the vehicle is turned off. My Van has 60000 miles and is in good shape, and just had the whole thing serviced last week. I saw the comments about the fan blowing, but is this going to hurt the vehicle.
Each time I start car,turn the fan knob to 5 and set heater knob in heating or cooling position without turning on a/c. Is it right?
