87 TRANS AM WITH DIGITAL DASH, CAN'T GET ODOMETER OR GAS GAUGE TO WORK. WITH GAS GAUGE IM THINKING SENDING UNIT CAUSE ITS AT 1/4 TANK ALL THE TIME AND ODOMETER NUMBERS I HAVE NO IDEA. ANY HELP TO GET THE NUMBERS TO APPEAR WOULD BE GREAT. EVERYTHING ELSE SEEMS TO WORK BUT THESE 2.

THANKS FOR THE HELP

 

If a digital display is not lighting up and others are, then you need a new instrument cluster*.

If it is lighting up, but giving the wrong information, then I would check the wire providing the information to that gauge using a multimeter and a factory service manual set (which would give troubleshooting instructions). There could be a problem with the wiring, a connector, or the sensor.

*If you know how to work on electronic circuit boards, sometimes instrument clusters might have a loose solder connection or broken trace. Might take a peek and do a few checks with a multimeter.

 

I have a spair cluster that i put in.same 2 gauges not workin

 

Well then you would need a factory wiring diagram which would be a part of a factory service manual set.

Then look at the diagram and see how these work. Where they get their power from.

Then test with a multimeter.

Also don't assume it is not a problem with the instrument cluster (because of the swap having the same problem). I've seen some products that have a part which tends to fail and all or most older parts have the same problem.

But you don't know for sure until you can look at a wiring diagram and see how everything works.

 

thanks i will look into it..thanks for the help

 

yeah what year is your car... i have two cluster for camaro

 

87 trans am

 

i dont think my cluster would work since i know trans am and camaro are different kind of cluster.... srry.

 

Thats what i was thinking.I was wondering why you said that.=) but thanks

 

im wondering if you have gotten this problem resolved because i am having the same problem with my odometer, i also have a 87 trans am. the odometer just keeps flashing 9999999

 

Hi. I am wondering if anyone found a fix for this issue. My odometer also flashes 999,999 and will not give any other details.
