Under the dash behind the glove box(remove glove box)there is a vacuum connector with multiple vacuum lines of different colors,held in by a small nut on a long stud.Carefully remove the nut,and the vacuum connector,spray silicon spray into the vacuum lines,male and female ports.Replace the vacuum line connector back on.Also look for a vacuum line on passenger side of vehicle,near the firewall,and check the small check valve on the vacuum line and the vacuum line itself for sucking together,and breakage.If all this is o k,and the spray didn`t work,the control head for the temp control is not good

Vent door between the two sides isn't opening or the flex hose going between the two is off.

The temperature actuator has gone bad. You will need to replace and have it recalibrated. You could try and disconnect the battery for a few hours and see if it will reset it's self. But you will be in the same boat before too long. And will eventually need to replace it.
