Heater stuck on defrost?

On many cars/trucks this problem is noticed.
If vacuum is reaching the heater control then the likely problem is that one of the vacuum operated servo "motors" that move the internal doors in the heater box has failed. If no vacuum is at the control, check the line from the engine that goes into the firewall for disconnects, cracks or breaks. Control itself is also suspect but they don't go bad very often.
This details will help.Thanks.
