Lights on steeering wheel, intermediate shaft

[paulfischer]

Hello all,
2004 Suburban, Noticed tonight that one of the lights on the steering wheel for the controls is out. Is it replaceable????

Also had truck in shop under warranty for some clunking noise / able to feel clunking insteering wheel while turning at slow speeds. Found a TSB (00.02.35.003J) for it, and dealer took care of it. They said that a new fix was coming out. Anybody else have this problem?
From what I've read on the net, it seems to be a very common problem with chevy trucks.

Thanks
Paul
