just bought a new radiator fan. and its not working. i dont recall the old stock fan turning on either!. i looked in my manual in the electric wireing diagrams and seen two cooling fan relays one with blk/grn wires and one with blk/wht wires idk wher they are i know thers one relay in the fuse box in the engine bay. idk how to tell if they are bad! can sombody help with how they are bad? wher is the second one? what else would be my problem?

 

ok that helps prolly better off googleing it then asking a bunch of people that own miatas anyways aye.

 

I have an extra fan I can sell you cheap if yours is bad.

Sorry about not getting back sooner but I have been busy getting the turbo car ready for a trackday in the evenings.

 

If it's an NA you can jumper it and kick the fan on to make sure it works. If you jumper and it works, then the problem is your thermal switch. Doesn't work on NBs I'm sad to say. Miata.NET says jumper GND and TFA.

This is a wealth of info for t-shooting cooling issues:
