67 Heater blower fan (non-air)

[James M.]

I find the low speed setting on the heater blower to be extremely weak. The med and high speed work appropriately which I assume rules out an overall bad ground situation. While the low setting does work, again it is very weak.

In searching the archives I find a considerable amount of info regarding the air cars but not so much for non air. Where are the resistors located? And how best to get to them? Which one is the low speed resistor? Does anyone know the correct part number? Supplier?

Thanks

The heater blower resistor is located on the forward side of the inside heater case, facing the firewall (just to the right of the core pipes in the photo below). The resistor controls all three speeds, and all the usual vendors have them for about ten bucks.
