Blower motor runs sometimes. Everything else works fine. Blower works fine on automatic or manual, then sometime either will not work or works for a while and then just quits. No power to the blower motor when it stops. EATC error codes 51 & 53

The next time it isn't working, test for power and ground at the motor and see which one is missing. If neither, the motor is bad.

My first thought just because of age. Plugged in a new motor, and got nothing. There is no power at the plug when the thing fails to work.

How do you know there is no power? Did you test it?
