Hey folks, New to the board. Just picked up an 08 Sierra 1500 SLT. Love the truck, but having a problem with the sunroof. When I bought the truck last week, I never tried out the sunroof since it was around 10 degrees outside. Now, the weather warmed up but the sunroof won't open. When I press the switches, nothing happens. No noise from the motor or anything. I called the dealership, and a service manager said something about "programing the sunroof". He made it sound like it was a matter of holding down some buttons, and that it was in the manual. I couldn't find it. I have an appointment on Monday to have them look at it, but I was hoping I could figure it out before wasting my time at the dealership. Anyone have any ideas?
