A constant "thump, thump" sound is made when the blower fan is turned on
and the air does not come out of the overhead vents. The switch light is showing green when it changes over, but the air is not being re-routed.

A twig may fave found it's way into the blower motor cavity, this can happen. You may have to drop the blower motor and fan out to check and clear any obstruction.
