Put the big black fuse back and do you get the clicking noise?
The clicking is a relay that turns the fan on. So it could be the relay or the fan.
I replaced the thermoswitch yesterday, but the fan still did not kick on as the temp gauge moved 3/4 way to Hot.
When I used the paper clip to test again, this time the fan wouldn't come on, but I heard a clicking sound from the big fuse box on the passenger side engine compartment. I pulled the big black fuse from the box, and tested again, and the clicking had stopped.
Also, when I turn on the a/c, the radiator fan started also,, which it did not use to do before I replaced the thermoswitch. Do I just need to replace that big black fuse?
any ideas?
thanks.

I get the clicking noise when the fuse is in...but not when the fuse is out. Does that make sense?
thanks.
Here is some more reading for you on the Miata's cooling system - http://www.miata.net/garage/CoolingSystemProblems.html
Did both fans come on when you turned on the A/C?

Use a multi-meter and check the power at the cooling fan connector with the AC turned on. If you're getting voltage at the connector, it has to be the fan's fault. If so, repair it or replace it. If you determine it's the fan and decide to try repairing it, see my blog post about how I repaired mine. It might helpl.

One fan is the primary cooling fan the other is comes on when the A/C system is running. With the A/C on both fans should run.

even though the fan has worked on 2 different occasions?
Do you have a meter?? (I think this has been asked before)
Check to see if you have voltage at the fan motor connector.
thanks for the laugh.
and all the help!
going to oreilly's..they are going to let me use their meter to test current.
