I bought a 2005 Chevy Silverado (4-door) and recently had the transmission rebuilt...and when I got the truck back, the clock was messed up with the wrong time. I didn't get an owner's manual for the truck when I bought it, so I'm in the dark as to how to set the clock. And I don't want to go buy an owner's manual just yet. Could someone please give me step-by-step instructions on how to set the right time? Thank you veeeerrry much!
