What causes a blower motor to stop running?
Most blower motors ground through the case of the motor when it is screwed into place or by a small ground strap from the case to the body of the car. Over time, the ground connection can become corroded or loose, causing the motor to function intermittently. Lee Sallings is a freelance writer from Fort Worth, Texas.
