I have dual a/c for front and rear seats. Air is blowing from all vents. A/C and heat work fine in the front. Today, I discovered that no cold air is blowing out of the rear a/c. We tried all combos with control from the front to controlling it from the rear. What's wrong and how do I fix it?
SOURCE: rear a/c blowing hot, front a/c blowing fine, cold air
that is true, however there are doors under the dash that direct the air. it is apparent that at least 1 or 2 of theses doors are stuck or none functional. they are either operated by a cable or servo motor. unfortunately if it is a malfuntion motor that will have to be replaced. if it's a cable it could be that it come off and can be put back on. if it's just a jammed door then you can do this yourself and just fix the jam. these componants are located under the dash. when taking aprt the dash becareful because the are often times plastic pins and clips that can be broken during removal of the dash panel. take your time, chance are you will save your self some money. good luck. please rate this....thanks

I have the same problem with my 2002 Durango. After accessing the rear HVAC unit you will find that there is a rear electronic actuator that operates a plastic door inside the duct system. The door switches the rear system between heat and cold. I had two broken items, the white actuator connector has a tab that broke off and the door inside the duct has broken where this connector fits inside. I am still trying to find the parts on line. I do not know what the part numbers are for these two items. Hope that helps, it seems to be a typical problem with the older durango's.

you cant adjust it ,this requires the dealers computer to re set it,or a phyiscal control has packed up like a vacumn pipe has split where it pushes onto the valve that controls the flap in the heater unit.

I really can't be sure off hand, but what you wrote looks like the control valves are sticking(these flaps allow air to go different directions at the vents). its located at the heater core(towards the left side of the heater core) under the plastic just under the dash. you can manually move them, encase they are stuck, they do stick sometimes. while checking the vent doors, make sure your vacuum lines are connected. also check to make sure your vent hoses are tight. I hope this helps
When I turn on the heat in my 2004 mazda mpv the front air vents blow heat but the rear air vents are blowing cold. I have adjusted every setting is there something I am overlooking.
