    i have a couple questions one is fairly easy and the other may prove difficult.

    I have a 02 1500HD silverado crew cab. What is the best service guide for diagrams and such on how to do things like take the dash apart and such?

    Now the hard one:

    a couple weeks ago the vent control stopped working. I think it may be a stuck vent or somethign else. It is currently stuck on defrost (whcih is ok since it si cold as heck right now.) when i switch to front, floor., etc nothing happens. I notice that the center of the dash pops up some after a period of time. Right where the center defrost vent is. It Literally bows up. I think it is related to the ac\heat issue. I know and fear i will have to take the dash apart to fix it. I did not know if the vent is mechanical with a motor actuator or not.

    thanks for any help you can provide.
