 Run the EATC self diagnosis first. It should point you in the right
direction.

> Hi  all..
> Just noticed when I went to use the a/c on my '90, that it wasn't coming
out the vent. Instead all the functions only come out the defrost.
> Could this be that tinny little diaphragm that has the vacuum line going
to it?And has the arm attached to the other side? Just curious as I have a
spare from one of my other SHO's and thought I would ask before pulling
stuff apart..
> thanks
