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

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
