If you have checked for voltage at the motor and a good ground at the motor and it doesn't run then it must be the motor.

Try removing the connector at the motor and then hook a jumper to ground and another from the batt.

Also your post is a bit confusing?? You say it won't work at all and then later you say that it does work?? Can you clarify that?

Thank you for clarifying that for me. You are awesome!!

Wow, what a dummy I am. Should have realized when he said that the brushes checked ok that he had taken it out and bench tested it.

well thats only my guess , with all he said , it was a little confusing..

the fan is before the filter..it is possible that something got in the air box..like a rodent etc..
