Recently bought this truck used from a Chevy dealership; just rolled over to 90k miles, overall in very nice shape. Checked the A/C to make sure it was cold briefly when on test drive, seemed nice and cold. Long story short, i was sitting in the passenger seat and realized that even with the A/C set on cold for both sides, I was getting only hot air from passenger side vents. Coolant level was a little low (thinking it might be a vacuum issue)...refilled with no joy. Should I be patient to see if an air bubble in the line passes keeping actuators from flipping, or is this something more serious? Stepper motor maybe? Simple disconnect of the battery to let everything reset? Any insight someone can give on a similar issue would be great!! Thanks much in advance!!

Re: 2004 Silverado 1500, 4.8L, LS...
This is a common problem it is the pass side blend door actuator sticking. sometimes you can unhook battery for a few put both controls on cool hook batt back up and crank up the hvac system will automatically go thru a learn mode and this can reset it if it stays stuck you will need to replace it

Your computer has sensed a component slipping in your transmission. At that mileage I would recommend a rebuild. The 4L60E is notorious for a weak sunshell anyway. I recently rebuilt mine and the spline ring was broken, but had not stripped the spline teeth out of the sunshell body yet.. There are fixes for the valve body for this code, but with your mileage, I think you would be wasting your time and probably sooner than later would experience another failure if not a complete failure.
Hi, This looks like the Pawl in the gearbox has been broken/damaged or even left out when the box was overhauled. It lock the gearbox whilst in park so acting like a brake. It could have occurred if someone put the vehicle in park whilst still moving. Hope this helps? Press the Blue button please to appraise My FREE! Effort. Thank You! Paul 'W' U.K.
