The AC blower and heater/defroster blower are two separate items. Probably the AC fan is stuck or burned out. It's located IN the dash, unlike the heater blower. I don't envy the person that has to dig it out to diagnose the problem.

And this should have been posted in the engine-mechanical-electrical forum, or maybe the interior forum. Maybe one of the moderators can move it.
