Hi All,

My 2014 chevy suburban LTZ had a "ground issue" on the ""computer"" (don't know which one) after it completely died and wouldnt start and after the expensive repair (500$) my radio and park assist are both intermittently working. When the radio goes out i get a "park assist off" on the dash and the radio and all sounds just die. I brought it back and apparently it has nothing to do with the repair the repair man did but im not so sure about that. Also the back heated seats are not working at all and they always worked 100% before but that's not a concern to me because i don't sit there. I feel the issue might have to do with a ground or bad fuse somewhere but again i'm not sure.

Any help is greatly appreciated

 

In my '11 the rear parking module is under the pass. seat and radio amp. is in the console. I'd look around there for a grounding point in the console area, don't have a schematic for a '14 .
