When operating my car in cold weather (generally below freezing), the temperature gauge will periodically rise nearly to the top of the scale for a time, and then drop back down to normal. As the car continues to get warmer, it does this less and less. The heater will only blow out cold air while the gauge continues to rise, and then finally blow out warm air when the gauge drops back to normal. In warm weather this problem does not occur at all. Any theories as to what causes this?
