Well FOR THE FIRST PROBLEM YOU PROBABLY NEED TO REPLACE THE THERMOSTAT IT IS MORE THAN LIKELY CLOSED SHUT NOT LETTING COOLANT INTO THE BLOCK TO CIRCULATE THE HEATED COOLANT 2ND THE UNIT IN WHICH CONTROLS THE TEMPERATURE OF THE INSIDE OF THE VEHICLE IS OR MAY BE BAD I WOULD START WITH THE THERMOSTAT FIRST BEING THIS IS USUALLY A MORE COST AFFECTIVE SOLUTION GOOD LUCK!

Vacuum controls this circuit and leaks will cause blend air door to default to defrost. Check for bad check valve or hose leaks under hood first as these are the easy ones to get at and under hood heat causes deterioration.

1999 durango vent control switch will not let AC blow threw vents only defrost


Usually this is a problem with the blend doors under the dash. You either have a vac leak, a dead motor, or a faulty door.
The control opens and closes the doors to direct air thru the heater core and evaporator core along with directing air thru the vents.
When a problem occurs, the default position is the defrost vents to make sure the windshield remains clear.
You can do an internet search for "repair durango blend door" for more info.

Air blend doors do not work. Air blows from defroster vents


check or loss of vacuum to mode control switch in dash ac control. these are not blend doors, they are air flow control, a blend door controls the air temperature not where it comes out.

No heat - ac stays on blowing through defrost vents


If you have the heater directed to the windshield, the AC will turn on. Move the control away from defrost.
