You might have a water leak somewhere. Check to see if your vehicle is leaking any water after a quick burn for 15 minutes or so. If you have a leak then your water level in your Radiator is going down and you are losing pressure in your system. This makes it hard to keep the cabin heat at a nominal level. Hope this helps, that was my issue with my 2003 Alt. Good Luck
