I need to re solder the connections to my 93olds instrument panel

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..!!

Good Luck.

Check your fuse box does it have a breaker or a fuse for the dash cluster? Might be a bad breaker or some corrosion on contacts /

I have a 96 Olds Cutlass Ciera, and my fuse box is in my glove box. To the left, there's a black panel that says "Fuse Panel." Not sure if there's another one or not.

CHECK THE CLUSTER ELECTRICAL WIRES.COULD HAVE KNOCK THEM LOOSE WHILE REMOVING THE RADIO.

that's what most people call it, go to the local salvage yard get one off a 92-93-94 olds, chev luminia

Your Vehicle Speed Sensor has failed and needs to be replaced.

Here is an example of the part at Autozone...

It is in the HVAC housing just to the left and below the blower motor. You will have to Remove to right sound insulator panel from under instrument panel to see it.

It is not the computer.

If you take the dash apart and remove the digital insturment panel.., use a soldering iron and re-tin.., or heat the solder connections on the back of the circuit board.., just enough to briefly melt the solder.., to re-establish good electrical connections. You specifically want to pay attention to the IC Chip on the circuit board.., which is a 14 pin IC chip that is Black in color.., and measures about 5/16" x 3/4" usually labelled IC2 on the printed circuit board. You can start with this component and re-try connecting to the harness in the dash to see if it works.., if it works.., great.., if not.., just go ahead and re-tin all of the solder connections on the back of the circuit board. The 14-Pin IC Chip is usually the main source of the problems with this digital dash panel.

The solder joints in the instrument panel occationally go bad, you can read about this on neons.org. The only semi-permanent solution is to re-flow the solder joints on the cluster, or swap it for a newer model.

Don't throw away the dash yet!!! I had the same problem with my 93 S-10 Blazer. My son in law(who is a computer guru) took a look at and found several loose solder spots. He redid them and it has been working fine ever since. Check around for some one who would take a look at the soldering on the board and I am sure they can fix it right up. Good luck KS
