Qater is accumulating in the heater box. Their is a drain that drains condensate from the heater bax and lets it drain on the ground it's on the fire wall and can be seen from under the car it;s a hose that flatted c\shut and the water is supposed to seep though it but it can become clogged, I use an air blaster connected to shop air to blow it out and let the water out you can use a wire too. once the thing is draining a vent cleaner can be bought at an auto prts store to flush out the mold that may be causing this problem and it's a spary that is sprayed into the ductdown and it works vary well as long as the drain is cleared first.

No air from front dashboard vents

likely to be a vacuum problem from the engine compartment to the thing that controls all the heater flaps in the dashboard .. thin hard plastic pipe from the passenger side of the front of the engine compartment to passenger cabin tends to get fragile with age/chafe somewhere and break/chafe a hole, you lose the vacuum to the actuating flaps & then air doesn't come out.
fairly easy to replace as long as you use the original pipe to pull the new one through

If no air comes out any of the vents in front, it could be the blower motor or a blend door problem.

2004 Dodge Grand Caravan SE front vents suddenly not working, what could have caused this? All fuses are fine, and the defroster vents still work, they will even blow out cold air, but not the main vents!...

plurbaby236, The venting system for the front of your vehicle is controlled by a vaccum line coming from the engine the rear is electric. You may have a broken vacuum line in the engine compartment. When this happens the defrosters are a default setting. Check for a small vacuum line going through the firewall, usually near the middle and follow it. You may find that it is broken. A quick repair is to take a small piece of rubber hose that fits snuggly on the plastic vacuum hose. Good luck with this.

2007 Chevy Uplander Rear Overhead A/C Vents Won't Work

Have you checked the Aux switch near the bottom of the center control console.
There should be a knob with: Aux, Off, 1, 2, 3. This is the switch for the rear AC blower.
If the driver wants to control the rear AC, use the 1, 2, 3 settings.
If you put it on Aux, Than the rear AC is controlled by the passenger in the back seat using the extra controls located on the Overhead DVD player. (The front AC must be on the rear to work)
