2007 Yukon SLT: Instrument Cluster Question

[Sanfran327]

I got this truck about six weeks ago and love it so far, but yesterday I noticed a mechanical sound coming from the instrument cluster. It is a pretty faint sound and isn't really bothersome, but I'm trying to figure out if this is a normal operating sound or if there is some sort of problem with my cluster. I'm new to American cars and SUVs in general, so I'm not familiar with this thing yet.

Any insight would be appreciated.

My Mom's Escalade makes a faint mechanical sound, but that's when you first turn the engine on and the needles light up and do a really cool sweep. What times do you hear yours, constantly or intermittent?
