2017 Yukon XL - No Dash Cluster Lights and Info Screen

[tmurray4192]

My 2017 Yukon XL has no dash cluster lights. The analog gages work. Also the Dash Info Screen is dark (no power). I have checked ever fuse box 3 times. The large "fuses/Relay-rectangle shaped" not checked. I did look at grounds in engine bay and on bottom of the frame. This happened after I left pressure treated lumber in Yukon for 3 days during the hottest and humid days this past summer. I had condensation (big drops) on all my windows. There was a video to reseat the entire fuse box which i haven't tried. I did run my ac for 5 hrs in the driveway. I also ran the heater on high when the humidity dropped to normal levels. Not sure what to check next.

I have a follow up. I hope this helps someone if they have this issue. After test every fuse with a meter, tearing apart my dash and checking every connection related to this issue and cleaning all the grounds. I found an article from GMC mentioning this issue i have is a known problem that can be related to an software issue or bad ICP (instrument cluster panel). I ordered an used one and bingo everything worked with the exception of my mileage is blank. I have to find out how I get the mileage stored in BCM or ECM into the used ICP. Not sure if the wet lumber mentioned had a hand in this issue.

It will need to be programmed to your VIN to get the mileage from the computers. White Automotive offers this service, but you have to mail it out. It's possible your local dealer may also be able to do it also, but I'm not aware of any aftermarket DIY solutions at this time.
