Cooling Fan Replacement
 

Hello all, glad to be part of the forum. I have a 2010 Mazda 3 Hatch. My Cooling fan does not kick in, even when I put on the A/C. I replaced the Coolant Temp sensor checked the Fan fuse I even manually hooked up the fan to the battery and it works. Next step would be to check the relay, but for the life of me I can't find it. Is the relay or the fan control module that silver box connected to the fan shroud? If true, do I have to replace the whole Fan? If I have to replace the fan, is it dificult? Does it come out of the bottom or the top ? Thanks guys......

The silver box is the fan control unit. You should be able to just replace the control unit.

Thanks for the reply.....I have had two Mazda techs tell me not to call that silver box a Fan Control Unit or Module...To them it is just a plain fan motor...This is where my confusion lies.....Everywhere I look for Mazda parts there is no fan control module, it is just the whole fan assembly....

Well, they need to read the workshop manual, because that's exactly what it is, & what it is called in the wiring diagram. Altho it appears to be incorporated with the fan assembly, its not a seperate part.

Once again Grim, thanks for clearing up the confusion. You were a lot of help...

Did you get this fixed?
I went thru 3 different ones. One would stay on, one would 2 would not turn on. All brand new. I tested it with the battery and it works. So... I don't understand this. Fuses are good, replaced thermostat, water pump, cooling sensor, im on the edge
