Thanks Nick. It’s f n freezing out no garage. That’s a bitcg!! On my way to Fla. providing we don’t get hit with a storm when I arrive home. I will check it out!!O-Kaaay. It would appear to be a small orange/red dot at the base of a bolt that is used to attach the blower motor mounting flange to the heater box. Now me, being the curious sort, would be personally inclined to gently remove that screw, and all its companions, and lift the motor up and out to see what the fibre material that composes the heater box looks like. Be majorily ironic if the squirrel cage fan on the end of the motor id happen to catch itself a squirrel. Or if it is an extra washer that was placed under the screw because of rust and,new, was cad or bright plated and catches the light just so.....................

Thanks for all Dez
