Ac switch

[preyes86]

So half of my dual climate control switches light up and the side that lights up is the passenger side. So when I turned my heater on that's the only side that had hot air blowing out of the vents. Is this a fuse or a do I need a new ac switch?

Now don't take this wrong. Look at my signature and see my age. I am a man or guy but have never been a bro unless it was my brothers. LOL!

Ok, now on to try and help. Have you had the battery go dead or unhooked recently? If so the BCM sometimes has to be reset with a correct scanner. Sometimes even with no battery problems. Did this happen all of a sudden or gradually?

I just bought it about a week ago so not since I've had it I remember that side used to light up but the radio didn't light up and the speedometer was screwy and had dead lights also so maybe that had something to do with it?

If just climate control try this:

Instructions

1


Turn the ignition switch to "ON."

2


Press the "Auto" button on the climate control panel. The button is located in the top left corner of the control panel in most Tahoe models.

Press the "+" button on the left side of the climate control panel to increase the desired temperature setting.

4


Press the "-" button on the left side of the climate control panel to decrease the desired temperature setting. The system automatically sets all climate control features to the proper settings to maintain the desired temperature.

Mine doesn't have the "auto" button

You do have actuators that control blend doors so any number of things could be going on but I lean toward the BCM because of the other numerous dash problems. I would never ever throw parts at it. Have it checked by a qualified tech and then post results here. Always post problems and fixes in chronological order. Like the first of your post was only about climate control and did not have any info about the other problems.

Thanks as soon as I get it checked out I will let yall guys know as soon as I do

 

[OR VietVet]

The least expensive attempt would be the BCM reset. Check pricing at dealer and other shops.

Awesome info thanks

 

[OR VietVet]

That's ok, bro. LOL! Sorry, couldn't help myself.

 

[preyes86]

Hahaha

Ok so I found the problem after a lot of research and you tubing! It was the blend door actuator for the driver side. It wasn't the switch because the fans would work and the light being off within the control threw me off and made me think it was something else. I checked all the fuses and they were all good so I finally tracked the actuator down under the kick panel and when I was messing with the harness connection it started working so that's when I knew it I had found the problem!

 

[OR VietVet]

And there you have it. Glad you figured it out. Now maybe the actuator is good but the connection is bad. Easier fix and less costly. Sometimes things under the dash get crud in them over time and just a good clean connection will fix. Also, make sure when you plug the harness in that the pins align and slide together tightly. Sometimes on the connection the pin on the harness will push out of the holder instead of sliding together and then either cause a bad or intermittent connection. Good luck.

Yessir I'm gonna get some dialectic grease from auto zone to make sure it sits nice and snug. I just really recommend starting to troubleshoot any temp problems with the blend door actuators .
