On a late model Beetle last night I was driving down the freeway and it was cold outside. For a good half hour the heater stopped working. No air would pass through the vents at all no mater how many times I moved the heater control knob up and down. The hot air would not go. It just stopped all of a sudden when I had the heat on half way. Then by the end of the road trip the heater returned back to normal. What happened? The heater is purely mechanical. All it is, is a lever that opens up a little door inside the heat exchange tubes. It's got a cable that runs to it. The cable wouldn't just break and fix itself in 1/2 hour would it? So what would prevent the air from passing through?
