04 grand prix gt blower works fine at any speed. had radiator, manifold and heater core flushed and refilled with new coolant, not the red stuff but the green coolant. worked fine for a few days and then no heat at all. i changed out thermostat and again heat for a few days then no heat at all. made sure there were no leaks and that coolant level in radiator and resivoir were full. any thoughts?
