Hi,
My truck's AC started acting strange yesterday. Seems like it works fine first thing in the AM. But in the PM, the driver side vents are blowing hot air, and the Passenger side vents are blowing cold air. I am assuming it's the HVAC Control Module ? Has anyone else experienced this? Am i thinking correctly ? Any help is appreciated.
Thanks, Lindsay

See the forum "2500HD/3500HD Trucks & Drivetrain". Look for thread "HVAC issues" by Kennedy.
