I belive your right about the baffel. It could be a vacum issue. Just a thought.

Vacum leak or a faulty vacum pump will cause it to default to the defrost position also.

4x4 works fine (or it would still be at job site lol) NONE of the settings change the outcome, any combination......just defrost.

How would u determine its the vacum pump? I would assume this would be the easy fix as oposed to taking the dash apart for the bafels or doors?

mine did that , was only a loose electrical connection on the vacuum pump. I unplugged it and plugged it back in and it has been working fine since.

Low/no vacuum will cause the htr. & a /c to default to defrost only.
