Is your blower motor blowing any air?

The "Blender" vent actuator may not be operating. A large number of questions on here seem to be centered on Older GM's ( all makes can have this problem but GM by far seems to be the most common) The last two I repaired was in the blender sw the vacuum ports became restricted....( Def-AC-Upper-lower .. etc) ... and one was the vacuum actuator under the Dash ... Royal PITA ... good luck ....
