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.

Cooling fan does not run?


At the main fuse and relay box, check the 30A EGI INJ fuse. If OK, the main relay closes to apply power to the cooling fan relay. Next, check the 30A FAN 1 and FAN 2 fuses.If OK, power is being applied to the fan control module. The PCM processes engine coolant temperature sensor input and sends a signal to the fan control module which, in turn, causes the cooling fan motor to operate. Fan failure could be caused by malfunction of the cooling fan relay, the fan control module, the engine coolant temperature sensor, the cooling fan motor itself, or the PCM

Radiator fan cycles continously. Fan radomely comes on and off frequently and has consistently gotten worse. Because of intermittent problem, Mazda was unable to diagnose problem. Any advice would be...


First, intermittent problems are the worst! I would look for a bad or loose connection. Does the fan ever run consistently? If you turn on A/C most cars will run fans continuously, if yours works ok on this setting then problem is isolated to temp control (fans ok, wiring ok, relay ok) The temp switch would be probably be faulty (or connections). If your fans cycle even on A/C setting then you are looking at a complete electrical inspection. Switches, wiring, fuses, connections, relays, fans...everything! Hope this helps and good luck!

2001 mazda mpv overheating both fans at not working PLEASE HELP!!


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.

Engine code states fan relay. How do I know which one to replace? MPV 2001 Mazda


Run you A/C on the high setting and watch your cooling fans. If they aren't running, take a known working relay of the same type and replace the high speed relay. If it starts working, there's the relay to replace. If they run on the high setting, do the same with the low setting.
