Why don't my fans turn on?
What would cause my fans not to turn on? I've noticed that when the engine has been running for a while my temp gauge sits right on the 210 mark and my oil pressure drops to 30. But when I hit some open air (highway) my temps drop and my pressure goes up. Every time I pop the hood I can never seam to see the fans on. I'm not overheating it never goes beyond the 210 mark. Ideas?

Also, do you never hear the fans engage at all? If this is the case, check the fan relays.

these cars have two-speed fans and you can hardly hear them on low-speed. even with the car off they are barely audible. why don't you turn on the AC and check to see if they come on.

I never heard my fans either untiul a friend programmed them to come on earlier with hp tuners. I know for a fact they never came on because when I heard them the 1st time I knew I had never heard that noise before. Stock, they are set very high. My 93 LT1 would get near the red zone on the gauge before fans would come on. I think its rediculous they are set that high.
