Max AC

When I turn the selector **** from normal AC to Mac Ac I don't notice any change in the amount of air being moved? What could cause this? Please help.

Max AC won't move any more air than when in normal mode. It just recirculates cabin air. You should hear the change in the air intake under the passenger side dash going from normal AC to Max AC.
