Question about 2011 Chevrolet Equinox

Open Question

I have a 2011 Equinox LT and heat is coming out of dash vents and floor vents but front defrost doesn't work

When you press the front defrost button and the fan goes on no air comes out of the top vent it comes out of the dash vents.

SOURCE: All Air Conditioning blows our the defrost vents

Some thing you could look at would be this. The control is usually fed by a vacuum line or small hose thats is connected to your intake manifold.
With a cold engine,look for a skinny vacuum hose that runs from the intake toward the fire wall . It should be going inside the cab and connecting to the A/C vent control.Some times the hose becomes disconnected or splits or cracks due to heat under the hood.
Thats usually the trouble.
I hope this helps you.

SOURCE: 2003 Trailblazer No air from front face vents

first check to see if you have power going to the actuators when you switch the switch to it location if no power replace controller if you have power and no movement from actuators replace actuator. if actuators move remove hvac box and check for broken blend doors.

SOURCE: Blower air just through defroster vents, not front vents

The problem is that the plastic lines that the air flows through get frail and cracks and breaks.What happens is when the hose breaks you loose vacuum and the system reverts to defrost mode.You should be able to see it from under the hood on the passengers side.You will have to find the area that is broken and then go to the parts store and get some rubber hose that will fit over the plastic hose.Take a piece of the plastic hose with you so you can get the right size hose to fit over it.This just happened to my 97 Astro van.I found the broken hose and repaired it with the rubber line and is working normal now.Hope this helps.Let me know what you find out.Good luck.

I have a 2011 Chevrolet Equinox LTZ and my question involves the heating/ AC unit. The air flow seems to be very strong through the Defroster but for the dash vents and the floor it seems to be much s


Defrost has been stronger on all types. Just the way plenums are made. Clear that wind shield first. As long as you have plenty of heat to keep the cabin area warm to hot, it's OK. I wouldn't woory about it.

My 2012 Chevy Traverse will only blow on the floor not upper vents or defrost.


the flipper in the dash won't change it to the other vents. maybe worn out. vents could be plugged. there should be something inside your dash that when you press the button or change the setting on the heat diverter it should switch from vent or floor. it's plastic and wears down or maybe jumped the flipper thing to move the heat thru the vent system

1996 Montero Heater Blower not working


I assume your heater setting is electric control, if so either your defrost and floor heat switch failed or wire problem. For the air not hot, check the heat control valve on the top of the hose it should be in front of the firewall. I don't know your car is using mechanic valve or electric control valve. Anyway check there first. Good luck.

Check the actuator motor and rods on the heater box inside. The motor moves the doors in the heater to direct the heat to the area you request. It is a small motor on the driver side or in front of the heater above the dash.

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.

Defroster & floor blowers don't work but front facing vents do


There are what they call mode door's these days they have a electrical motor that turnes the door to different posistions...sounds like yours is become broken. It would depend on your expertise in the ac & heating system area to replace the part. Sometimes easy and most of the times the dash has to be removed.
