2015 Surburban issues

[trayedog]

Having the following problems.

 

1.  Compass does not display most times.

2.  Trailer brake system indicates not working sometimes.

3.  Seat does not vibrate when getting too close to cars.

4.  The battery is not charging properly.

I would work out the charging issue first, as everything else you describe is dependent on electronics that could be sensitive to power issues.

Check the connections at the battery and alternator and have both checked with the appropriate testers. 

Most auto parts stores in my area will do that for free.
