I need some help, made a rookie mistake and threw out the old heater box before noting whether it had the opening for the "rheostat" as most suppliers indicate on there listings. I suspect that mine didn't have it as the old blower appears to be a 2 speed (3 wires w/ one being a ground).

Am I correct in assuming that with the 2 speed blower that the system didn't have the resistor?

 

Mine has a 3 speed blower and it only has 2 wires on the blower motor. It has a 3 prong connector and a 1 prong connector on the front of the heater box.

Do you have the 3 prong plug and 1 prong plug hanging under the dash?

 

If you have three wires in the engine compartment, it's a two-speed. Why did you throw the heater away? They can almost always be restored.

Rule #1 in restoration, never throw anything away until the completed car is driving down the street.

 

Hey 2+2, Why does the 2 speed have 3 wires in the engine bay and a 3 speed has only 2 wires there?
