Getting used to new to me 08 Alpha. Trying to figure out what trim level it has. Leather seats, sun roof, Nav radio, subwoofer in the back cargo area. I have found a few of the electrical gremlins I have read about. Dome lights work intermittently with the front doors so I am assuming it is the door switches. Radio will shut off if the dome light comes on when I open the door but otherwise it will stay on. I am trying to figure out which cable to use if I put in a new radio, if it is the Monsoon radio it uses the GMOS04 I think, but I don't know if monsoon radios came with a Nav setup. I will change the terminals on the battery as soon as it is warm enough to feel my fingers outside. I have figured out that I need to replace all the backlights in the master control on the drivers door and the temp control **** on the dash. Really happy with it so far but a few little things to work out and a lot to learn.

 

Does it have a rear locker button in the T Case controls. If not, probably a Lux, most common 08 Alpha.

Run a Car Fax on it, or take it to a GM Dealer and have them print you a build sheet.

 

Thank you, didn't realize that was an option.
