Fan Don't Come On

My car heats up pretty quick and when it does the fans don't turn on un less I turn the A/C on. So I need to drive with the A/C on all the time so the engine stay cool. What can I do to fix this?

Nope, fan mods. = Miata thermoswitch or manual switch, inside the car. If you drive around with the lights on (even just running lights) the fans come on sooner.

Make sure all the relays are plugged in all the way. That's pretty simple. You can also check them fairly easily. A shop manual will give you instructions.

Go to www.iluvmyrx7.com if you don't have a shop manual.

Yeah, drive around with A/C on or parking lights on and the fans will come on earlier. It's the easiest way to do it. But the fan switch mod is not really all the difficult anyway.
