I have a 2007 ford five hundred, in the summer when I'm driving the Air condition is blowing cold but when I stop or parked it blows warm? In the winter it takes my heat 10 minutes to kick in once I start driving? And when I stop or parked something it get cool? But if I hit the gas it's hot? What do I need? Some people said a AC compressor but that have nothing to do with the heat

Sounds like two separate problems. The A/C might just need a good servicing, if the charge is low when your engine speed drops the compressor speed also drops and if it hit a predetermined setting the low pressure switch will cycle out the compressor momentarily until speeds pick back up. The heater sounds like a air pocket in the cooling system, check the coolant level cold and refill if needed, sometimes the system has to be pressure flushed to get the air completely out.
