Hi all, The heater on my '69 works insanely well (for an air-cooled VW!) and it starts putting out hot air quite quickly. However, I have a failed thermostat (it's terribly expanded) and I wondered if my flaps weren't screwed up. (A compromised thermostat expands, and should open the cooling flaps all the way.) I took off the right side elbow at the fan housing, and as far as I can tell, the flap is totally open. I rotated the shaft that the flaps ride on with pliers--it's at full stop in the direction represented by a mark on the "front" of the shaft moving up to the top (i.e., full counterclockwise as viewed from the left side of the car, or, for the physicists, "to the right" according to the right- hand rule, assuming you're facing the front of the car and standing upright). Does that check out? My flaps are open, right? (Hey! no jokes.:) The engine doesn't appear to run hot, but the heater vent under the rear seat will put out painfully hot air if you put your hand against it while cruising down the road at, say, 45mph with outside temps at freezing (of water, that is). -Greg '69 & '71 Squarebacks '63 Beetle
