Default Electronic Heat/Air Cond Problem

Good evening,

I have a problem with my brother in-laws 95 coupe that I hope some of you can help me with.

Currently the air is blowing out of the defroster vents and floor vent no matter which selection you make on the control panel. For example, you can select the dash vent selection but the air flow never gets redirverted. The temperature control works as does the fan speed selection- it's just the air flow directors not working.

We unhooked the battery and reconnected it but notheing changed.

Any help is appreciated.
Thanks,
Dan

Believe you are in the default mode. You have a problem with a vacumn leak or possiably the programmer. Check under the pass/side fuel rail cover. There is a vac/tee that may be disconnected or broken?

I checked for codes and none were present. I will check under the plenum cover, as you suggest. Thanks,
