NBS gauge cluster

It's a loose wire. I bought a escalade cluster that the gear light goes off sometimes, and I have to push down on my dash where the plug is and it will come back on.

If its a 03-06, that's actually pretty common for that PRND123 screen to fail. Sometimes it will intermittently go out before it completely fails.
 
Yes it's a 2005. What's the fix for the problem?

New cluster, or send it off to someone who can repair it for you.
I wish I could help you. I can replace the bulbs and the stepper motors, but not that screen.
Honestly, I would just wait until it completely goes out. The one on the 04 Silvy at work has been acting up for more than 3 years now, and it still only acts up sometimes.
