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 speedometer, odometer and gas guage keep blinking on and off on my 1992 Cutlass Supreme, sometimes only part of them will go off and sometimes all of them how can I fix this?


It sounds like it is the wiring harness for the dash. You will have to take the dash out very carefully clean the contacts on the harness with electrical cleaner and then reinstall.

I have a 96 Olds Cutlass Supreme that intermittently won't start


If the lights on the dash all come on but the engine wont turn over it could be a problem with the VAT security system. Your key has a little chip on it between the teeth and the handle. This is a common problem with GMs', often just replacing the key is necessary but sometimes the VAT module needs to be replaced.

I need to replace some dash lights in '87 cutlass supreme


The other screws are behind the woodgrain panels on either side of the speedometer cluster. The panels are held in place with metal clips and are difficult to pry loose. I did it by using a small plastic wedge that I found in a junk pile and once I had a place to start, I worked each corner of both panels until pried out. These panels could break, so go slow and be patient.
