Hi all. I recently bought a 95 Trans Am with LT1 and I was wondering why both of the cooling fans turn on right after i fire the car up, Even if the car is cold. I live in Massachusetts so it gets pretty cold around here. Are the fans programmed through the computer? How would i know if the stock program has been changed? Any input would be great. Thanks.

Is the check engine light on? Sounds like it's in maintenance mode. The fans are on high right?

No, the check engine light is not on. There are no trouble codes present.

sounds to me like someone has disabled the check engine light. To test the light pull the Air Pump fuse under the hood. This should make the light come on. If the light don't come on that is the problem.

Would the light come on immediately?
