    Default !988 pontiac grand prix cooling fan fails to come on

    I have a 1988 ponyiac G,P, and the engine cooling fan will not come on. I have used the info from chapter 3 in the haynes manual and still can't determine the problem. I have checked the fan motor and it works. It seems I am not getting any signal to activate it. I have checked the fuse under the hood, I have tried to jumper the coolant level switch to see if it would activate the fan and have tried grounding out the temp. sensor and nothing seems to show me where the problem is. Any further help would be greatly appreciated.

    mauro27 - If you turn the AC on do the fans come on?
