How do you fix a faulty digital instrument panel on a 93 olds cutlass supreme?

Remove the Digital Insturment Cluster from the dash. Take it apart and check the solder connections on the 14 pin IC chip located on the printed circuit board. This is the most likely cause. Resolder the pins. If that dosent work, resolder every thing on the board. Other than leaking capacitors ive never found anything wrong in these units other than broken solder connections. Usually the unit will flicker on and off depending on ambient temperature and bumps in the road or hitting the dashboard. This is due to broken solder connections on the Integrated Circuit (IC) listed above.
