Where is the turn signal flasher unit on my 1989 Oldsmobile Cutlass Supreme


Should be under the dash just to the left of the steering column, sometimes, if you have 2 flashers, you can turn on the emergency flashers and listen and feel for the click, your turn signal flasher is usually right next to the emergency flasher.

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.

Dash board keeps blinking on and off


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.
