Question about 2006 Chevrolet Trailblazer

1 Answer

Air diverter only diverts blown air to feet or defroster.

The air blower on my 2006 Chevrolet TrailBlazer will only divert blown air to the feet or to the defogger/defroster. It will continue to blow air on the other settings but the source will remain at the feet, or if the selector is moved to the appropriate setting, the defogger/defroster. It appears that all fan speeds are working properly.

My 2005 ford focus ... the defroster button is on defrost and no air comes out of the defroster to the front windshield but blows out at your face and feet??? trying to get this fixed before snow flies...

well if it blows out at your feet you know the blower is running (as it's a common problem for blower motor shaft to rust up from AC condensate drain plugged up) but in your case it sounds like the air diverter damper arm actuator is broken or just stuck (yes it can rust too) you'll need to remove toe space cover to gain access to it on passenger side floor move heater contol back and forth to watch it move Or (NOT) you may have to free this up or replace it

95 chev. pickup. Cool air comes out at floor. Cannot divert any air to the vents or defroster vent. Can feel warmth on the black plastic box like thing near the floorboard so I know there is warm water...

It sounds like the actuator that diverts the air may have gone out. I would suggest replacing the blend-door actuator so that your air will go to the right places. The blend door actuator shouldn't cost more than $150.

2003 Grand Prix not blowing hot air. Does the heater coil need to be replaced? If so where is it located?

If the heater coil was bad, it would be leaking radiator fluid... probably into your dash/floorboard (depending on where it is installed in your model car). There is a switch that diverts the hot radiator fluid through the heater coil when you want heat. There is also an air diverter valve that helps to mix the hot and cold air. The fluid valve is controlled by the A/C settings control. The one that you use to choose between heater/air conditioner/vent/ defrost. The air diverter is controlled by the temp mixing controller. The most simple explanation is that one of those valves or the controller of one of those valves is not working. If the hot water cant be diverted through the heater coil, the coil can't exchange the heat (warming the air). If the air diverter (hot/cold controller) cant move to add heat, then all you will feel is air from the vent side (from outside) or from the A/C cooling the air.

I would guess that its either a controller or one of the valves themselves. Odds are, it is a controller. That tends to be what malfunctions first.

Defrost blows constantly? How do i fix it?

does it blow through the defrost vent only when you switch to vent/floor or does it blow through defrost and vent/floor? is it a switch that is just electric or a manual lever that you slide? the manual type will have that problem if the diverter or the linkage behind the lever(in the dash behind the panel......may be able to access underneath) becomes broken or disconnected so that the air is diverted to defrost regardless where you move it.if you can get to it, you will see what is broken or maybe a fastenerr fell off.

The AC Diverter does not appear to be working. 2003 Impala

It is vacuumed controlled. The vacuum hoses from the control go to a vacuum controlled actuator that is inside the venting.

The ac was blowing out of the vents, but now just recently started blowing out the defroster and wont change no matter where I set the selector. what happened?

You may have lost vacuum to the air diverter. Or the diverter is plugged with something. Been sitting all winter?

I put a new stereo in to my 04 trailblazer and now the air will only blow out of the defrost vents and the bottom and no longer will it blow out the concel vents. i looked and the vents are inline and not...

Sounds like you may have disconnected the cable that diverts the blower ducts up and down. Sorry but the radio may have to come out again to access it.

The air selector for the heater/air conditioner moves but the air only comes out of the defroster. I need to know how to remove the console to see if the connector is broken. Can anyone help?

under the dashboard just above the gas pedal is the actuator rod to divert airflow from defrost to floor and vents. This may have come detached. move the wire/rod until it can be re-attached on the diverter door and wire-tie it on.

Air condition

Have you checked the diverter doors under the dash??
It sounds like a vaccum hose may have fallen off your vent controller.
I have had similar problems and found that the air WAS moving, but it was all going up through the defrost vents at the windshield.
A quick check of the vac. lines showed that one under the glove box was pulled off.
with the engine running, try setting the air settings to all the options ( vent/floor/defrost..etc..)
See it you can feel or hear the diverters moving under the dash..
