I have a heater problem. My heat blows normal and very hot once the vehicle starts to warm up. The heater works just fine until the vehicle has been running for around 20 minutes or so. The heater instantly switches to cold air and blows nothing but until the vehicle has been shut off and has a chance to cool substantially. I haven't been able to pinpoint if the the thermostat is opening or closing at this time. I just know after an extended amount of running time the heater stops blowing hot air. I have recently installed a new thermostat and radiator. Problem existed before and after both changes.
