If door is stuck you can maybe unstick it but you have to take the air distribution box out which requires removal of the dash

What diverts air to defrost. Air comes out vents and floor. ac works and heat , but won't go up to dash vents. The flaps are working.


You just THINK the flaps are working, but apparently the top vent is not. These multiple flaps are controlled by vacuum and you have a line off to that particular flap. This means the flap won't open and the vacuum leak, whether you can hear it or not, is making you lose MPG also, though slight. The vacuum line could be cracked or disconnected from the flap or at the vacuum block on the back of the lever unit.

Cool air comes out the vent when I put the heater


temperature flap most probably stuck in cooling position. normally the potentiometer in the flap motor causes the problem. cleaning the potentiometer normally solves the problem.

Ac and heat will not blow threw vents just floor and defrost


Sounds like your selector switch is messed up to select where you want the flow of air to go. When you turn the switch to where you want the air to go does it work on floor and when you turn the switch to vent it doesn't?

A/c blower issue. 2202 chevy trailblazer


your blower resistor bad or the blower motor control switch is bad. no air flow from top vent make sure vent open.because you can manual adjust them not to blow air on you.if all is good.you have leaking vacuum hose or vacuum actuator.or air door stuck.the AC and HEATER control switch.is bad.its not allowing vacuum to open air door.

Rear tops vents on 2005 trailblazer dual ac system do not throw air. rear control switch was replaced and blower motor too but still does not throw air. any suggestions on what could be the problem?


it wont be the blower motor, sometimes the switch. but you replaced the control switch already, the only thing left would be the actual actuators or a wire problem. like a stepper motor controlling a flap to let the air out those vents. SO either the stepper motor that controls your rear air flap/vent is inop, or its not recieving the power or ground coming from your control switch due to broken or damaged wire.

There is a flap in your heater box that is controled by your vent switch by your heater controls. listen for a vacuum leak. that is common and hopfully the problem. there is vacuum lines that control the vent door that redirects the air to your vents.

Has your dash been messed with recently? if so i would check there first. you should hear a hissing if thats the problem.

Otherwise these also are common for that door flap to break and not switch NE more. thats the only 2 things that i can think of off th wtop of my head to be the problem. this would require the whole dash to come apart if its this problem
