So stuck in traffic today the miata decided to act up. Temp gauge made it to 12, so I put the fan on full hot (that was fun) and pulled over. Fans weren't kicking on unless ac was on. Jumped the TFA and GND pins to check the fan, fan works. Left it jumpered for the rest of my drive. So bad thermoswitch? Or bad relay? My thought was if it was the relay even jumpering it wouldn't work, right? Are the relay and switch o'reily/ vatozone parts or do I need to hit up the dealership?
Under Cooling switch.... that's why I couldn't find it... http://m.oreillyauto.com/mt/www.orei...1963&ppt=C0039
Thermoswitch is what solved my fan issues on the 1990 I had. Bought it at Oreillys.
You migbt also check to see if you have a "lazy" radiator fan motor if you still have the original motor. Those fan motors don't last forever.
Both fans seem to have equal "oomph" when on.... how does one test laziness?
Amperage test will tell you if the fan is running in spec.Quote:

My 94 needed a new relay a month or so ago. Got it on Ebay for 6 bucks. Autozone had it in stock as well but 27.
The hight tech method is: Wear a heavy glove and try to stop the fan with your hand. The lazy fan should be able to be stopped with relative samll amount of pressure.Quote:

This also works for testing the disposal in your sink.Quote:

Damn lazy and shiftless fan motors...
