When running my heater on the highway my temperature gauge will start going towards cold. When it gets to the C mark the heater starts blowing cold air and the ETC light comes on. I can pull over and stop and let the car idle for awhile and the temperature needle moves back to normal and the air is warm again. But the light doesn't go off until I turn the car off and back on again. It will run OK for awhile and then does it again. Do you know what is going on and what to do about it? Signed cold and confused.
have the same problem?
