What's up guys...picked up a 87 GTA with a digital dash..have some provlems...the Speedo tach works rpm battery oil gauge they all work...but the 2located on top of the radio do not..but ill get to that later...my concern is the ses light does not come on or the temp gauge does not work on it..the top 3 squares on top where the ses light should be don't turn on when I have the key in the on position...so I wanna see if I can fix that any help would be awesome thanks.
