when the temp is down on the car it blows heat fine, but as soon as the temp rises above 100 it blows cold air. it has a new rad,heater core. i put 3 new thermostats in to see if thats the prob, but no, new hoses. the head was checked to see if it was cracked or the head gaskets were gone, but they are fine. it is not air locked. and the whole system was fulshed about 3 times. i had it to 3 garages but they can not find the problem. help 3 kids ,winter time, and a car that blows no heat.

| 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? | |
