Newbie Mack Posted January 30, 2021 Share Posted January 30, 2021 2011 Mack cxu Starting and running fine.. dashboard just froze in place. All gauges stuck where they were, digital screen blank/not lit up. Any troubleshooting advice? I’m looking at the fuse panel under steering- Quote Link to comment https://www.bigmacktrucks.com/topic/65719-dash-board-froze/ Share on other sites More sharing options...
General Ike Posted February 1, 2021 Share Posted February 1, 2021 On my wife's last Escalade (2011) I had an issue where the amp for the radio which also controlled blinker noises and dashboard alerts wouldn't sound either, wouldn't reset. No sounds, no music. Simply disconnecting the negative battery cable did not solve the problem due to residual power in the system. So, I disconnected both the positive and negative from the battery and connected the positive and negative together to completely drain the system (of course making sure that the cables didn't make contact with the battery). Waited about 10 min. Hooked everything back up and bingo the amp and the ECU reset. Only crappy part was reprograming radio stations. I didn't want to pull the center console apart to trouble shoot the amp only to find out it needed to be unplugged and replugged, so I tried this first for what it is worth.

Newbie Mack Posted February 1, 2021 Author Share Posted February 1, 2021 Worth a try... thanks. I have an Acadia that has that exact problem your Escalade did. I bet that would definitely work for it Quote Link to comment https://www.bigmacktrucks.com/topic/65719-dash-board-froze/#findComment-468093 Share on other sites More sharing options...
