'06 Silverado with the old style dual climate control. Yesterday while heading to work, the driver side vents started blowing hot air and the passenger side vents were still blowing cold. When I cranked it back up this morning, i had no issues on the way home. The driver side just flipped to hot air again a while ago. Any idea what's going on? Maybe a simple fix I can do myself?

I turned the A/C off because the hot air was unbearable. I tried turning everything off and on. Slid the thermostats up and down. It only "resets" when I turn the truck off and back on.

My father truck did the same thing. He had to change some air intake valve on the a/c. Because it would stay open and let the hot air flow. This is a common problem on Chevy's trucks.

This Youtube video should answer your questions https://www.youtube.com/watch?v=fuGVAE3YWlg

I have a 2006 Silverado, was having this same problem. I tried your solution & it work just fine. I'm still interested in finding out what causes this problem. Do you have any suggestions?

I changed my actuator also and it didnt help. $150 wasted. Before you do anything, pull your fuses and let it sit! This happens when you have a voltage drop such as a bad battery or loose or dirty conections. Pull the fuses and let it "Reboot" so to speak. Dont waste your money like I did.

It's the little motor that controls where the air goes, you have a couple of them under the dash. The part is cheap and you can do it yourself in an hour or so. If you do it be sure and do what the instructions say about not Appling any power to the motor until it's in place and tightened down.

Actuator harness or the actuator itself, common problem with the dual zone system in those trucks.

I had an 05 Sierra and my wife had an 04 Yukon, and both did the same thing periodically. Most of the time if I just turn the engine off and back on it would go back to normal.

Blend door actuator.

When I had a 2005 Silverado and the blend door actuator went out, I was only getting cold air out of the defrost vents near windshield.

It was about $300 P&L at the stealership.

Thanks fellas

If pulling the fuses for an hour works, that'd be what I call and easy fix. Never would've thought that would work.

I used to just shift to neutral, and restart the engine. Drove my wife nuts when I did that on the highway.

Then I bought a ford *ducks*

That's one thing I'll give a ford. They do have ice cold A/Cs. Then again, so does 99% of other vehicles in their first/only 3 years of operation. j/k

I guess I'm just an ole grumpy SOB, but why are there threads on this board about a/c's, hot water heaters, etc?

I seriously ask because if it's a truck, that slides it into an outdoors type vehicle used for hunting?

The old regulars are always there. Knowledgeable, but more importantly experienced, they are willing to lend advice whenever they can but are not prone to speak up with conjecture unless no valuable information is to be had. Each is known and respected for being as close to an authority about a specific subject or subjects as is available. They aren't easily excitable and are rarely verbose, but can be fiercely loyal to their ways and friends.

Then there are the frequent visitors. They share ideals, values, and passions with the old regulars but may lack the breadth experiences. They usually walk the walk and talk the talk. They are comfortable exposing some degree of ignorance in the search to gain experienced information. This group is more capable of fostering excitement, debate, and ambition about a particular subject amongst themselves and the regulars than the regulars are capable of alone.

From the outside the discourse may seem glib, short, or harsh but those involved understand the brevity. They realize that these often harsh words said with a smile and a chuckle are a sign of endearment and common ground.

Of course there are a variety of others that wander in. The lost and in need of help, the misguided or ill informed, the damsel in distress, the outsider with strange and different methods and values, the spectator just wanting to catch a glimpse, the salesman, the politician, the sheriff, and even an activist or two have all been known to drop by.

Those smart enough to show some minimal respect and courtesy are universally accepted and helped. Conflicts in ethics and values are even rationally debated and discussed as long as certain unwritten lines are not crossed. But those with thin skin, closed minds, malicious intent or blatant disrespect are either ignored or confronted by the frequent visitors noted above. And rarely when the truly egregious occurs it can cause the old regulars to rise from their seat and spit a stream of chew on the floor at your feet.
( an action likely universally understood here but few other places)

I use my truck to haul my 4-wheeler, boat, shite I kill and ice chests full of cold miller lites. It takes me to the hunting land, the lake and sporting goods stores. I would like to continue to do so, with a little air conditioning, until I decide to get a new truck. Before I went blow money that I could use to buy hunting/fishing equipment, I wanted a few opinions from the great OB.

Plus it's hot as shite even with the windows down and the wife doesn't want her hair messed up

Blend door actuator. Have changed out a few, and the passenger side sucks big time

Eta: Basically look at the spot on the dash between the radio and the airbag. From there, go almost all of the way in the dash to the window. It's in there
