Instrument cluster and radio failure

[Wmello]

I have a 2014 silverado z71 ltz with 74,000 miles on it. A few weeks ago my touch screen for my radio started freezing up and sounds system stopped working all together. Now my instrument cluster is shutting off completely and coming back on. I tried the g218 grounding issue fix and it did nothing. Please help!

This may sound odd, but give it a try and see if it fixes your issue. It may help, it may not. Locate the fuses/relays for the radio and cluster. Pull them out and make sure that they are not covered in dust. If they are, wipe the dust away. Used a can of compressed air and blow out the ports that the relays plug into. Plug the fuses/relays to back in and see if it helps. Years ago, I had a 2003 Malibu and one day, my DRLs kept kicking on and off causing the service vehicle soon light to pop on every time the lights would go out. I did the procedure above and it fixed the issue. It never happened again.

Welcome to the site.

 

Kind of sounds like your HMI module is failing. Once they go, they take most of your interior electronics with them.
