I have a bit of a heater mystery going on here, any advice is appreciated.
I've got an '82 RHD heater with a three position lever - Vent, Heat, Defrost. Its got a vent flapper in the upper section of the heater and then a heat/defrost flapper in the bottom. When I got the truck, the linkage to the lower flapper was missing, such that there were only two positions that worked - Vent and, uh, "not vent".
I bought a rebuild kit for the heater, as well as what SOR said was the spring for the lower flapper:
SOR shows this image is of the 73+ heater with the three-position lever, however my heater is different - there is no place for the spring to attach on the lower flapper and my linkage arrangement is different.
I did some booty fab to replace the linkage I'm missing - its the L-shaped piece you can see in shiny black:
The original looked something more like this:
So even with my booty fab linkage in place, something is missing, I think there should be a spring or something. I can't find any loop or hole or slot for a spring to install on the lower door, however. Help!!
