While driving my car yesterday, I noticed that I was getting full heat from my vents even though I had the temperature knobs both set to full cold. The passenger side vents were blowing cold air. There was no change as I moved the sliders up and down.
I see from searching this site, that the problem might have something to do with the driver-side temperature actuator. Before I tear open my dashboard, where is this actuator located? Is it repairable or would I need to get a junkyard replacement?
I think that you are looking for is the heater mode door actuator. You can check out a picture on rockauto. It is vacuum operated so check the air line and fittings going to it to make sure there is no leak.
You don't have to "tear open" your dashboard. You gain access to the actuators from underneath the dashboard. Find a photo of one and then you will easily spot them under the dashboard. They have a few small bolts and an electrical wire(s) connector. Buy a new one, they are not expensive.
I lost heat on the driver's side of my 04. Replaced the actuator and the problem was solved.
Thanks for the replies. When my wife drove it a few days ago, she told me that she was getting lots of cold air. It looks like the actuator might be an intermittent problem but I'll have a look for the actuators anyway.
The lamp for the temperature control sliders has been burned out for a few years so, if I'm really ambitious, I have to open up the dash to fix it.
my impala was doing this a few months ago. after checking out the actuators and finding they were good. my problem was low freon. it wasnt in the red on the gauge but it still wasnt enough to get the drivers side cool. the passengers side had no problem. once i recharged it they both work great again

Sorry if i'm an a**hole, but i tend to speak whats on my mind and the truth as i see it.. May not be right but it seamed right.
I was trying to find a video about changing the actuators but haven't found anything yet about the Impala dual system. It does look like the L & R actuators are the same but replacing them doesn't look easy on the Traverse. The Chilton diagram appears to show them in a relatively accessible location on the Impala.
Since the actuators seem to be more likely to fail (gears & electric motor) than the sliders, I'm going to try to change the driver side within the next couple of weeks.
