Hi guys l have a 2014 Silverado that is done all crazy things no sound , my cluster will go black dead ,
light on the steering wheel and comands no response i can not get phone calls engine will be driving ok but no info . I have a bully dog conected to the truck so I get speed and info from it . Then after two or three seconds will be back and go until I get to stop . The dealer could not find the problem so I replace the HMI module and the receiver I replace the cluster too I did the big three upgrade check all the grounds and a new battery. The cluster is working fine now but I still lose the sound,if someone have any advice thank you
