My gauge needles are flashing blue and not working, speed, gas oil pressure, etc.

Also not working is read out information like milage, miles per gallon, miles left to drive on current gas level, precent of oil left before oil change, heated seats.

My heated searing wheel is working along with nav, radio, back up camera, etc

HELP PLEASE!

Hello,

This sounds like the battery voltage has dropped below minimum operating levels I would start by changing the battery here is a guide to help you do so.

Hello,

This is a common problem with the instrument clusters, here is a video that shows how to remove and install a rebuilt unit (on a similar car) that you can get from eBay or equivalent

Even replacing the battery with an AGM does nothing to fix this. Mine has a lost communication fault code, and works intermittently, with no rhyme or reason. I would think Cadillac would know how to make a reliable dash by now.
