Instrument Cluster is completely black/turned off - everything else working normally?
Just starting today, when I turn on my car/engine, the instrument cluster (odometer, rpms, etc) are all completely black/turned off but everything else including the entertainment, lights, etc are working normally.
This is probably related but I had to jumpstart my engine earlier (the battery needs to be replaced and runs out fairly quickly) so i'm guessing something might've shorted here?
Any idea on what's going on and what the fix would look like?

Link below might help, you should also see if you have any codes present.

For starters, if you have a battery tender/charger, hook it up to that for a bit and give it a go. If the battery is really dead, the car could be prioritizing power and only using the lowest draw of power/appliances.

Thanks - I removed the battery terminals and put them back again and looks like this did the trick. CEL is on now though so i'm not sure if it's related to that or recent work I did on the cams

I disconnected both main battery and aux battery for more than 30 minutes, checked additional fuse F64 and #43. Instrument cluster is still dead. Will try to find the scanner to find out what the codes are.
Quick question, the key fob was wet and dried later. The key is functional now, able to unlock/lock cars, start car. Is the key RFID the only mechanism I have to worry or is there safety issues disabling some of the modules tried by once wet key?
Thanks for your help.
