Thanks to this forum, I was able to get the coil rebuilt on my 57 chevy standard truck heater. Now that I have it assembled however, I can't believe that this was the orig design. The round coil accomodates a pretty strong little three speed motor nesting in the middle of the coil. That motor propels the fan that is mounted in front of the coil. The air flow is nothing but a dribble. The fan blade pitch appears to be correct and the fan blade rpm is more than adequate. Am I doing something wrong, missing a part or was this the acceptable amount of heat and defrost flow? Appreciate anyones experience with this as I am mystified. Thanks
