I'm new here, so this might have been covered previously. If it has, please direct me to the solution as I don't know my way around the forum yet. I have a 2004 Grand Prix, NOT supercharged. The cooling fans come on when the A/C is turned on, but they don't come on automatically when the coolant temp rises. Any suggestions? Cooling fan controller? Relays? I can't find information anywhere on how to troubleshoot this. Thanks for the help! The car has a little over 120K miles and is otherwise in great shape. No other engine issues.
