Heat comes out of center console when air conditioning isn't on on 1999 Saab 9-5

In summer, if I don't turn the air conditioning on, heat comes out of the center console. Also if the windows are open in summer this heat coming out of the center console happens also.

I have the same issue, and from what I heard from a dealer, it's just the car's normal venting system. Not a very good answer, I'm still trying to figure out how to fix it. In the winter, I solve the problem by putting the A/C on 70 degrees and directing it towards the defroster and that makes the hot air less noticeable. The summer is still an issue.
this is a blend door issue easy fix
