Back to this.....
Warmer weather, so now I want to use the dash vents and/or the A/C. I noticed the airflow was weak coming from the dash vents. After moving the selector around, it seams like defrost is ok, but as soon as I go to floor/defrost, floor or vent, I always have airflow coming from the dash vents. When I set the A/C to recycle, the airflow from the dash vents is weak. I had to put the fan on 3, where 1 or 2 is normally more than adequate.
I haven't looked at anything yet, but was wondering if anybody had experienced this? It's like the blend door is out of alignment/adjustment.
What I might do is swap in my old one, as the selector switch was working fine. See if it does the same thing.
