08 Silverado Digital Dual HVAC Issue

Hey Shawnvw,

I see you are the go to guy so far on this topic. I have a 08 Silverado with a digital dual climate control. The drivers side blows ice cold air and the passenger side blows hot air. I was able to get it hooked up to a ALLDATA REPAIR computer and get the code that are wrong, but its like reading a foreign language to figure out what is wrong. Any advice/help you could send my way would be great.

Thanks

Place the ignition switch to the OFF position.
Disconnect the scan tool.
Install the HVAC control module.
Connect all previously disconnected components.
Start the vehicle.
Wait 40 seconds for the HVAC control module to self-calibrate.
Verify that no DTCs have set as current DTCs.

I know this is a few months old but there are instructions for the control module at the top and instructions for the actuator at the bottom.

I also wanted to say thanks for the instructions and to add I picked up a AC Delco replacement actuator from Rockauto.com for $40 shipped, beats the dealer and gmpartsdirect.com prices.

Thanks again
