I have no heat. The vehicle runs at its normal temp (around or just under 210). I have changed the thermostat about 2 years ago. I checked the blend door actuator and it is working. I had the cooling system flushed last week. Both hoses from the heater core get hot which to me suggests that it isn't stopped up. Before I had the cooling system flushed last week, I did have heat when the vehicle was running at 55mph but when I was going slower or especially at idle speed it would blow cool air but now since I had the system flushed I have no warm air at all at any speed.
My thoughts are either air pockets in the system or possibly the flap the opens & closes for hot or cold air is broken. I don't know if the vehicle has a bleeder valve or not. It has the closed radiator. Is there a fuse that controls the hot air that could be blown or is there some other logical explanation for my problem?
have the same problem?
