Heater Motor

The 4-wire 6-volt heater motor on my 46 coupe bit the dust and needs to be rebuilt. Since it seems nobody in the Tampa area wants to mess with it, (unless someone out there has a good 4-wire unit for sale), I may go ahead and get one of those universal models however the problem is that they have 2 wires-one for power; the other for ground. Considering I have the 4 wire switch, I should be able to find the terminal that works the high speed for the motor and make the connection. Will this work or am I overlooking something? Appreciate any assistance. Steve
 
Hi Vic. Although I have the switch, I will see if they possibly have the heater motor. Thanks. Steve
 
. The motor you need runs forward for heat and reverse for defrost. The replacement will only give you hi and low so you only need a 2 position switch.
 
V8Bob on here has a napa part number for a reversible fan motor that will work in an original 42-48 ford heater.

Thanks for the info.

Yes, NAPA # 655 1022. This is a two wire motor which will require mods to the stock switch, or the use of a reversable toggle or rotary non-stock switch.
 
Thanks Bob C and 46fatford,
I intended to answer but "stuff" happened! :)

FYI, the NAPA 12 volt motor # is 6551022, 6 volt # is 6551021.
 
Steve, I don't think its silly, I'm just getting my voice back and hopefully getting over the cold I got riding in Vic's 39 last weekend. If you find out what works for fan & switch let me know what you've done, so I can get heat in the 54.

Hi Hal. I certainly will. It looks like NAPA has the 6-volt motor in stock so I'm thinking if I hook the one wire to the terminal for high speed on the 4 terminal switch I should be ok. I'll let you know how I make out. By-the-way, it was a great time at the Moonshine Festival. Did those trim rings fit the 54? Steve
 
I don't know how the case on the NAPA motor is, but if the opening for the wires is large enough, you should be able to install the reproduction 46 heater motor harness and use your original switch.

The switch for the hot air heater in 1946 or the fresh air heater for 1947-1948 would give you 2 speeds without rewiring the motor.

I would think that the slow speed would be nice for most conditions in FL. When I drive my car in weather above 30 degrees, I have to have the heater on low and crack a window or it gets too hot in the car.

I do have a NOS switch for the 2 wire motor. Send me a PM here or on the V- Club site if you want it.
 
There is a fella in Massachusetts that rebuilds these. In fact he purchased two "cores" from me about a year ago. I am still trying to find his information in my pile of notes. In the meantime maybe someone from the area can shed some light. I'll keep looking. I have another one for him.
 
Hi,
on your hotwater heater motor. If you go for a single speed non reversable motor here is what you will have;

no defrost air

you will have two speed

you can use your original switch

the switch cover/knob slides off so one can slide on proper colored switch. Not all years are the same

heater sheet metal shells are not all the same as the 41 have a small hole in the lower left for a defrost push-pull rod...

The mounting brackets for this type have only one hole, for the switch. Later brackets have two holes.


I hope this helps.
 
Hi, I am restoring a 48 ford convertible that has a 1947 1948 fresh air heater. Does anyone know if that is a two or four wire motor? Also missing the H, DEF, and AIR control knobs. Thanks, Chuck
 
Steve, I have rebuilt several of these, normally it is not a bad job unless the armature is gone. usually can be done for 45-50 dollars plus shipping. i am in NY so usps is probably 5-7 dollars. Thanks Rick
