    Does anyone know who can repair the heater blower motor from my 1964 Dodge 440?

    If you have not seen my thread on How to remove the fan from the blower motor, I solved it and posted the new information with pictures for all of us who have these old mopars. It is listed in General Discussions.

    It’s probably cheaper to get a used one.

    I bought a new one from Napa, but had to fabricate how it was mounted. If you have a couple of pictures of how it’s mounted in the housing it might jog my memory on what I had to do.

      It is mounted on this plate. See the first picture.

      The plate slides over the heater/blower motor's shaft and is attached by two nuts. Then the fan slides down over the plate above that.

      I see that there is available one for the 1964 Dodge Polara from Four Season, but I am not sure if the mounting is the same as the factory style.
      If you have experience with that one, let me know.

        If I remember right the bolt spacing was different on the Napa motor, had to modify the plate and splice the wires. Wasn’t very expensive. That was 13 years ago though. Not sure exactly what you’d get now. I’ve got a good Napa store here that will work with you, older guys on the counter.

        Thank you PRND21 for the information.
        I have emailed Four Seasons about there heater/blower motor. Also I am going to check with the NAPA dealer near me and see what they might be able to help with and I going to see if I can find someone around here that can rebuild the one that I have.
        Thanks to everyone who replied to my post.

        What does not work on it? The brushes look good... You sure it just does not need the insulation on the wires replaced, lubed up and reassembled. There is very little that can go wrong with these... the fuse will blow before you can do much damage to these old DC motors.

        One of the wires that connects one the brushes is broken. But I laid them together before taking the photo. I tested the motor before disassembly and it did not work. Not being an electrician, nor having any experience with electrical motors, I was thinking of having some else repair it. The wire insulation looks good and that is something that I can check further. The bearings seem to be fine. There is a lot that I can do, but this isn't something that I have knowledge of. Tho to be honest, I would really like to learn.

        Do you have a Service Manual?? All though the manual doesn't show heater motors, study about starters. They are basically the same thing as a motor. If you took this apart, you can put it back together.
        Clearly that wire needs fixing, it looks attached in post #1. Take some fine sandpaper and run it over the armature and the small copper area. those 2 Brushes ride the commutator to spin the whole thing.
        I guess you didn't play with slot cars as a kid???:poke: Good Luck

        Yes I do have the 1964 Dodge Technical Service Manual and No I never built Slot Cars. Tho I did go and raced them a couple of times at the public slot tracks.
        Taking your advice, I will study the starter motor assembly.
        Always will to learn something new to add to my metal tool kit.
        Thank you for the information.

          Alternators are kinda built the same way, The FSM has the story on that. Good Luck
