If you want more info on the blower mode I can look it up in my papers because when they turned it on at the dealership they gave me a sheet on it for the information so just let me know

If you have it that would be great! The air in my seat coming out is cooler than the air coming out of vents set on low. This sucks and itís not even warm out yet.

Only if you have it set to recirculate inside air. Not sure about the controls on yours.

lol. Yep just drew in the smokers smoke.

We have some roads we travel that usually between Feb and March there are skunks hit regularly. If you set the air to recirculate inside air well before you get to those spots the stench is not nearly as bad, but you have to leave it to recirculate the inside air for a good while even after passing by those places.

the reason why it blows cold sometimes and doesn't at other times is because it may probably be set to pull air from outside. if the temp outside is 64 degrees for example, and you set the AC to 60 degrees with the air circulation coming from outside, the air will feel warm. but if you set it to recirculated, it'll cool down faster

Ok so it seems to be acting up again. I have the fan on high and it barely comes out of the vents. Like the fan is blocked. I can hear it blowing but not much coming out of vents!!!

i found on the wifes 2011 cruze she had a car garbage bag in the glovebox. which had also been sucked into the fans above the glove box thus killing airflow. maybe check the glovebox for anything of that nature? also how is the cabin air filter doing?

Recently replaced the cabin filter. Will check the glove box nothing comes to mind as to what could be in there.

Can you do some more diagnosing and post back? I don't have a gen9 Impala, but if the HVAC works like the gen8's, it sounds like you have a vent actuator (aka mode selector) problem. Can you move the vent selector knob to different positions, wait a minute, then see if the air flow changes in each of the outlets (defrost, dash, feet)?

A bad vent selector actuator could explain the lack of air coming out, especially if it's stuck between turning one off and turning another on. But it does not explain why the temperature is not right - that is controlled by a separate hot/cold blend actuator(s).

If the air temp is still an issue, do likewise with it, and adjust the temp knob(s), wait a minute, and see if the air temp changes, then report back.

This could imply multiple actuator issues, which seems improbable, but not impossible.

One other thought, is it set for fresh air or recirc? Again, I wonder if that actuator could be a factor in no air flow. Try changing that setting to see what effect it has. You can hear the effect. If you tear into the dash a bit, you also can see if it's moving.

When it was idling it blew antifreeze out, i paniced and shut off. Turned car back on let idle for a few and it blew again.
Where did the antifreeze come out? This might indicate some sort of over-heating problem, which can affect the HVAC air temp. For example, if the radiator cooling fans are not functioning properly, the lack of airflow thru the radiator can result in the motor getting hotter _and_ the AC not cooling properly.

When you noticed the air temp issue, how did the engine temperature gauge read? Was it in its normal position, or perhaps elevated?

So when i was driving it this morning i did switch the vent select around and it didnít seem to change where the air was coming from. Like it was stuck and not moving. There is cooled air blowing out but it is so minimal air flow!

Does anyone know where that actuator is located or how to service it? I would switch it out if itís not overly difficult to get to.

My temp on the car was around 180 i think. It hasnít done it since then. It does blow cold air more often then not! I would agree that it seems that some actuator is getting stuck and not allowing the fan to blow air through any vents.

The Chilton procedure calls for removing the "Evaporator and Blower Module". That's the box under the center of the dash that houses the evaporator and heater core. No way would I want to do that.

But I think that has been recommended in the past, on gen8 Impalas, but most folks managed to avoid all that. Instead, on the gen8's, the glove box was dropped and then the actuator was accessed from the left side of the glove box opening. It may have even been accessible with the glove box still in place.

The drawing for the gen9 (attached) shows the actuator forward and above the right side of the radio, much like the gen8. So it appears to be accessible via the glove box opening.

What I recommend is to drop the trim above the passenger's feet, get on your back and inspect with a flashlight to see how accessible it is. Look to see how hard it is to drop the glove box. For example, you may need to pull the trim off the dash, which isn't too hard, but needs to be done with care to avoid cracking the plastic. I've even cut a small hole in the glove box to facilitate access for things like this (rather than removing it).

In short, the key is to find the actuator and size up the job. Does the glove box even need to be removed? Then decide if you want to get a part and try it yourself, or take it to a shop. (BTW, on the gen8, a 5.5mm (ie, 7/32") socket was needed for the actuator.)

Also, inspect the wiring. Make sure the connector hasn't become separated from the actuator. Maybe all that's needed is to plug it back in.

HTH.

Doug
