Could it be the motor stops freezes up and then blows with regulator. I will do the test again today to see if is the motor or the regulator.

Either way I have very little heat coming for the cold weather predicted this week.

No, the fuse should blow, before the regulator is damaged, unless the regulator coils are seriously corroded..

Note:
You can jumper/bypass the regulator = gives full speed blower.
