Backlight Repair Service

Dark or Intermittently Working Cluster?


This is the most common repair required for the 1984 - 1989 Corvette Digital Cluster. Over time, the connector becomes oxidized and sometimes broken, and the solder joints can become cold.


Signs your cluster may need this repair

  • The four bulbs which illuminate the cluster remain dark, even with the ignition on.

  • When the ignition is on, the cluster remains dark and the info can't be seen

  • The cluster is dark with the headlights off, but works with the headlights on.

  • Sometimes, hitting the dash or hitting a bump causes the cluster to start working properly.

  • Shining a flashlight on the cluster causes the information to appear.

  • The cluster LCD panels are dark, but the turn signal and high beam indicators are on constantly.

  • The backlight bulbs are bright at power-on, but are too dim after that.

  • The backlight bulbs don't dim when they should.

  • The cruise control won't set.
