Question about 2005 Chevrolet Avalanche

Only getting heat out of my defrost vents

When I turn my heat on it is only coming out of my defrost vents. When I change the settings to floor or vent it still only comes out of the defrost vents only. What would cause this? It is currently -26 F with the wind chill today. Would this have frozen something?

Defrorstores stay on ,try to change to floor, ac, heat vent ,deforstores still on 1995 thunderbird lx blower motor works great.


Some cars use vacuum from the engine to open and close the doors that direct the air to different positions. It is possible that the vacuum line to the controls is cracked or disconnected.

Why is air coming from all three areas (vents/floor/defrost) regardless of setting?


There is actually two blend door actuator that control the opening and closing of your vents. Ine is located under the drivers side dash board. The is on the passengers side. Both are electric and I didnt have the money to replace them so i removed them and turned it with a pliers to allow heat to come out of bothe sides of the vent. Then come summer flip the little bar back the other way to A/C
Hope this helps

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.

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.
