Ive noticed this in a couple different series of MPVs. I have had several of the earlier generation MPVs and theres lots of sensors on these things. If one of those sensors goes bad, then the others will not work correctly. Check your manual and see if there are any additional sensors you have not checked. Also there is a site that I used to get help with my MPVs. Its and there may be a fix listed there. These guys specialize in MPVs. Although your relays may be working, they may not be receiving a signal from the correct sensor. Also from a little research it would appear that the cooling fans themselves have a tendancy to stop working. There are several people that are saying that they are wiring their fans to run manually. The AC fan seems to be the first to go and then the main fan. Try hooking the fans up to direct power and make sure the fans are not bad. Hope this helps...

There is a thermal fan switch on the radiator that drives the relay.

the things to check are,the fuse,the thermal fan switch,the fan relay and the fans themselves.
if they all check out ok,it is the fan control module that is blown.

Turn on your A/C, is at least (1) fan on? NO? You need to replace at least (1) fan, that is the AC fan. YES? Then at least you now you AC fan works.

Make sure you have enough coolant in your car. DON NOT OPEN RADIATOR WHEN HOT. The Coolant Switch will noever cut on if there is no coolant there to trigger it. You can find it where the thermostat housing is.

Next, get a 12V testlight and test the wiring going to the fans. BE CAREFUL NOT TO GET CUT MY A FANIF IT TURNS ON! If you have electricity, but the fan does not cut on you fan needs repacing.

2001 Mazda Protege cooling fan or thermostat

I am realizing that the cooling fan in this car is very important. It has two in case you didn't notice. The driver side fan motor is bad in mine and the only result is poor air conditioner performance in stop and go traffic. It's fine at high speeds. I would think the thermostat is likely the culprit in your case, but if the fans are not working at all, you should get those replaced. The motors may be bad in both, which could definitely cause overheating. I've been researching prices and you should be able to get the parts for less than $100 each and installation is just a couple of bolts on each assembly.
