Instrument cluster black
If you have the 3-Panel Digital Cluster, with the Fuel on the Left.., Speed in Center.., and Odometer on the Right.., and the Cluster is going Wacky.., works one minute then craps out the next.., take the dash apart and remove the Digital Cluster. Take your time when unplugging the harness behind the cluster, use a mirror if you have to.., to unplug it correctly.
The problem with this Digital Display is the Solder Connections.., at the 14-Pin IC Chip.., which is directly behind the Odometer Display on the main Circuit Board. When you get the Cluster removed.., again.., take your time.., and take the cluster apart.., so you get the main circuit board out. The 14-Pin Integrated Circuit (IC) Chip is marked with an IC2 on the main board.., which as mentioned is behind the Odometer Display. The IC Chip is usually Black in Color.., and is '@' 1/4" x 3/4" You will need a Soldering Iron.., @ a 30 watt with a pointed tip.., don't use a Soldering 'Gun'., too hard to use and too hot.., you don't want to cause yourself more problems by messing up the board circuit tracks by overheating them.., so it's best to use a smaller iron. It is a good idea to have some fine strand solder on hand.., but you should not need it.., all you want to do.., is to 'Re-Tin'.., or 'briefly' melt the Solder at all 14-pins of the IC Chip.., on the back side of the board.., to Re-Flow or Re-Solder the Connections of that 14-Pin IC Chip to the Circuit Board. That's all it is..!!!
I just repaired my 1991 Olds Cutlass Supreme 3.1.., 3-Panel Digital Instrument Cluster in this manner.., and it has been "Perfect" for a month now..!!
Take your time.., get it all back together.., and my bet is that it will be good to go for many more years to come..!!
