2008 gauge cluster cutting out....

[68ragtop]

Got a weird problem with my 2008 2500HD 6.0L silverado. The problem is more noticeable within the first few miles That I am driving it. The cluster will basically power out for a split second & come back on. I notice it from the sound of the stepper motors all dropping off, then all the indicator lights illuminate & the gauges go back to the normal readings.

After this power cycle,the airbag light will be lit, & I will have to unbuckle, & re-buckle. then the airbag light will go out.

I have a feeling if this isn't a common issue, its going to be a tough one to find seeing it happens so intermittently.

Sounds like it might be an issue with loosing a ground wire to the instrument cluster? My wife's has where about half of the cluster lamps go out. Then when you hit pot holes around town they will all come back on again till next time, they go out.

I wonder if they have any of the issues like the one in my 03 silverado had. That one had the shift indicator go out, & I found a bunch of cold solder joints on some of the resistors. Worked great after. That ones also had lights out in the cluster that I replaced.

On this 08, I have not caught the very moment it goes out, & I think its for a fraction of a second. What I catch is what I would call a "re-boot" all the gauges go to zero, & all the warning lamps come on. Then it goes back to the way it was before with exception to the SRS light being lit. Only way that will go back out is if I un-click, & re fasten the seat belt.
the illumination never goes out durring any of this on the 08
