Something about the vacuum linr being unattached, maybe from the firewall. im trying to figure out the same.
The main vacuum supply line is disconnected or cracked, probably near the engine. All the HVAC doors operate on vacuum. When there is no vacuum the HVAC system goes into defrost mode.

Loss of vacuum supply to the HVAC controller. The vacuum supply comes from the pass side of the engine and goes through the firewall next to the AC lines. It is a small black line.

On a dodge ram 1500 why does the defrost only work if its on high?
