Hey Sal ,Add your city and State to your profile ,somebody might know a place right down the street .Mike
A quick search will show that Sal is located in Winter Garden, Florida and supplies his phone number also.Sal,
Suggest you add your general location to your profile so you get local repair services. Post what kind of heater you have (is it an ARVIN?) and maybe someone will know a motor that fits and is available. Plus pictures would be useful.

Napa sells a 6 volt motor, #655-1021, for about $36 USD. Worked great for my 3 door heater.
C&G 800-266-0470 has them in their catalog. About $80, a fair price and probably less than having it rebuilt.
I think that you'll find that the motors tha C&G carry are only the 2 wire variety so will work in Ford heaters but will not change direction the same way as the 4 wire Motors do i.e. by reversing the field winding polarity.
