I needed to upgrade the main motor to 12v. All the standard suppliers for classic parts had them for around $60 or more. I found one at O'Reilly Auto for $31. fit and works just fine. Part number was PM354. 12volt, 1/4" shaft with a sleeve to make it 5/16ths if needed. I could not find what I thought was a close enough replacement for the defrost motor so I am installing a voltage reducer. I bench tested it. I was suprised how hot they get. Yes, it is said to be big enough for a blower motor. Here is my finished heater. I know the color is not correct but it will look good with the black carpet going in my cab. I have the good 6v motor if anyone needs one.

If you never tell a lie, you never need to remember what you said.

Let us know how it works. | | | | | Joined: Dec 2012 Posts: 72 Shop Shark | | Shop Shark Joined: Dec 2012 Posts: 72 | Hey Bart,
I could use that 6 volt motor. I screwed mine up trying to separate it from the fan. Can you send me a pm if you still have it and are willing to send it to California? Of course I'll pay for it.
thanks,
Dave
