SOURCE: a/c vents door control not working

Can you hear anything moving in heater when you move the switch to other settings? If not then the blend door is not moving to redirect air flow. There is three things that could cause this, 1 the control switch is bad or 2 the blend door acturator is bad, and 3 linkage for the door has come unhooked or broke, most likely its #1 or #2. First you need to find the blend door acturator and test light the wires to it, there should be 3, 1 hot with key on 2 only hot with switch moved, and 3 ground. If you got power from wires than the acturator motor is bad, if no power switch is bad.

SOURCE: Heat and AC vent problem.

most likley you have a vaccume leak somewhere but also the linkage to the door that that directs the air flow may be in a bind. another possability is the hvac controlls. hope this helps

SOURCE: vent in centre of windscreen not working i have

There is only one door. Air flows through the AC evaporator and the blend door diverts some or all of the flow through the heater core. For heat, the compressor is off under electric control and the non-refrigerated air is diverted through the heater core. The door is on a vertical axis and can swing to any position based on random corner turns, fan speed, mode, etc.

The blower on my a/c on 2002 chevy trailblazer only blows from the floor vents and the defroster vents but not the dashboard vents how can this be fixed. Also, it only works on 5


It sounds like you have two problems. First a question though; Is your heating and air conditioning control on the dash automatic (has two knobs that rotate and a display screen in the middle), or manual (has two levers that move up and down for driver/passenger temp and a separate fan knob and mode knob).

In response to the vents being stuck on defrost and floor, from experience i can say that the most likely cause is the mode actuator has failed. If your battery has recently gone dead, that could have brought the problem to the surface. When the battery has gone dead, the heating and air conditioning controls relearn all the positions of the actuators behind the dash when the vehicle has been re-started. If there is a position sensor failing (which happens quite often) in one of the actuators, the heating and air conditioning controls won't be able to learn the correct position of the actuator and (in your case) defaults to the defrost/floor position.

The only way to fix that would be to replace the actuator. I would like to know what type of heating and air conditioning controls you have (manual or automatic) before i say anything on the blower only working on 5.

AIr always comes out of the dash vents no matter where the controls are set.


Sounds like a vacuum motor problem which controls the blend door and its position inside the dash board area where the flapper directs air from the heater core to the defrost vents or the vents, or the floor, as directed by climate controllers on the dash. Good luck on this repair.

In my 1998 Honda Accord Lx the hot air does not come out of the heater vents in the floor, the same is true for cold air in the middle vents on the dash. The side vents on the dash work fine.

Heating / air conditioning control stuck to front defrost vents


There is a vacuum leak under the hood. Find the vacuum line on the passenger side where it comes through the firewall and follow it to the engine. You system needs vacuum to operate and without it the default setting is on defrost for safety reasons.

CANT ADJSUT THE CONTROL ON HEATER AND AIR


The controls for your heater/vent selection is inside the dash, behind the control switches you use to select the vents the heat/AC will come out.
When you move the selection levers, there's a few things that happen. Vacuum is applied to the doors (which are inside) and they open or they work using cables to move the doors or both. The different doors open, directing air flow to the vents selected.
Remove the controls from the dash (which should just be removing some screws, maybe a few small pieces of dash and pulling it out). The controls will be connected inside so they will not come out very far.
Just check to see if anything is disconnected and try operateing the controls with the heat on to see how they work.
Sometimes they just stick or the doors stick. This system is the way the 1991 models worked but since they are the exact same, it should be this way also.
Look it up in some sort of repair manual for more info. I find with these trucks, they don't heat very well using the front vents anyway. I find using the bottom vents work best for heat unless you need defrost.
The "heater" selection will atomatically use the bottom vents, "bi-level" AC will use the front and bottom vents if I remember right and regular AC will automatically use the front vents. For the trouble in removing these controls (the whole dash would need to be removed for repair) I probably would just live with the way they work if they do work atleast properly (enough heat and AC). If you find that you don't get enough heat or AC when in use, check the cooling system for proper operation and blockages/mineral buildup and check the AC system incase it needs recharging or you have leaks.

Air conditioning blows out of the defrost vents only


If this is the mechanical unit it is possible that the wire in the back has come adrift or the clip that holds the wire in position has come off and now the whole cable is moving.
Have a look at the bottom of the dash where the controls are fitted and move the control at the same time looking if there is any movement below the dash, take it from there
