I just fixed the same problem on my 96 park ave. You probably have a broken air mix actuator. There are 2 on the car but the one on the passenger side seems to fail most often. Open the glove box all the way down. You need to fold in the rubber stoppers attached to the back side of the glove box to release it all the way down. Once you do that you will see a silver metal arm that connects the actuator to the vent door on that side of the car. If you can move it back and forth, you have a broken gear inside the actuator. Local parts stores by me don't carry it so I bought mine through GM Parts Direct for $50 plus shipping.
your blend door which cost about $1000-1500
Smoke could be coming from the vents of your car for a number of reasons. You may have an internal car fire.
The Avalanche has dual controls for the air conditioning system. One control operates the driver side ac vents, and the other control operates the passenger side vents.
My ac blows only in the defroster and not any of the other vents i have 98 ford windstar 3.8 v6
heater core needs replacement
It is called condensation.
AC VENTS are in the correct position if they are open and free flowing. Some systems have a heat and an AC position for the vents. The AC position is so the cool air discharges from the vents higher on the walls or from the dash rather than floor or windshield in a car.
prior out with a flat screw driver
replace? why not fix it?
replace the temperature switch it i sthe one on the right of three in the middle of dash I have same problem on my 98 it took me like 6 hours to get to the problem but it worth
If antifreeze is filtering through your ac vents, other toxins could also be coming through. Don't take chances; see a mechanic.
smoky mist coming from the heater vents.
Your heater core has failed.
you probably need a heater core.
That is the correct spelling of the plural noun "chimneys" (fireplace vents).
There may be something blocking the deflectors from sending air up there.
Nope, that would be steam.
um...I know why no one has answered this yet, cos no one knows what the heck you are talking about!! Try rephrasing it!!!!!
There are 2 filters you access in the glove box. If they are dirty you get almost no air. Clean or replace them and be amazed at the difference
I assume you mean smoke and water are coming from the A/C vents. I suspect you are seeing steam and coolant. You probably have a heater core leaking.I assume you mean smoke and water are coming from the A/C vents. I suspect you are seeing steam and coolant. You probably have a heater core leaking.
If there is no heat coming out of the vents, but there is air coming out on a 2003 Mercedes Benz E-320, check the thermostat to make sure it is not sticking. If this is okay, check the heater core. If the heater core is bad, there will be water on the passenger side floorboard.
change the cabin filters
replace the heater core
Your heater core is leaking, Need to REPLACE HEATER CORE.
Coming out of the vents around 43 degrees
