PONTIAC GRAND PRIX COOLANT PROBLEM

2008 Pontiac Grand Prix • 78,000 miles

My 2008 pontiac grand prix just recently started blowing warm air from my heater as before it was coming out hot. Could you tell me what possibly could be wrong with it and what can I do to fix this. Thanks Andy

MAke sure the engine is warming up to operation temp (could be a bad t-stat) Also, make sure the coolant is full in the system.
