The heater shown by tclederman is the one I have. Denny, thanks for that advice. I think I will bench test these motors wired in series and see how that works before I spend $120 on two new motors. At this point I am not sure how much it will even get used in cold weather. I need to check on the year of this cab since it is not the original cab. I have the plate that came on it that I should be able to tell for sure if it is a "47" or "48".

If you never tell a lie, you never need to remember what you said.
