Sounds like your thermostat after you run the car awile feel around on your radiator for cool spots feel the hoses see if they are hot or cold. that will tell you alot about it hope this helps. Phil
It sounds like you have a blend door problem. This is located in the HVAC sysem it closes a door from cold side to hot side. sounds like a bad servo motor or a vacuum leake on that motor. Hope this helps you, please rank this solution
