I've had a 2005 Chevy Colorado Z71 Crew Cab for about six months now. I am very satisfied with it. I have a couple questions that I'd like to ask of other owners.
1) When I unlock it using the key fob the horn beeps three times. This started recently, I think after my wife accidentally set off the alarm. What does it mean and how do I fix it?2) I hear rattling when I traverse rough road that sounds like hardware under the bed. Is there something I should tighten down after 5k miles?
Any advice appreciated.
