I have a 04 grand Prix and my heart won't come on, do you know why?
Fan doesn't work?
If you mean, heat, I would check the fuse, the switch, blower motor and its associated wiring (in that order).
If your heart won't come on, I would recommend calling 911 or using a defibrillator. But if it's your heat that won't come on, the blend door could be stuck, or you could have air trapped in your cooling system. Check your coolant level,, check for coolant leaks, and bleed any air out. Is the fan working?
