Okay, I'm not being lazy as I did try to research this question online but found no answer. There are two fans on my 97 Miata behind the radiator (I've owned it less than 2 weeks). My left one (driver side) goes on when I turn the A/C on but the right one does nothing. I'm not even sure they are working when the engine is hot since I have never gotten out and checked with a hot engine nor have I heard the fans. Just how hot does the engine have to be to activate these fans? Also, shouldn't both fans be running?? Thanks.
