So my 1992 camaro's gas gauge showed beyond full for the longest time. I actually found time to check it out and the fix for me was easy (after trying several things for about a year). Took out the gauge cluster and found out where the cluster connects to the wiring harness ( 2 actual connectors / gas gauge on the left connection) had a metal prong that was bent so it would not make contact with the circuit board of the gauge cluster. I bent it back so it would make contact with the circuit board when the cluster was plugged into the dash and presto the gauge magically worked properly. Not reading past full anymore. No longer do I have to wait and start dying out at traffic lights to let me know that I need gas.

This worked for me on my 1992...not sure how the setup is for other years. Originally I thought I was a ground wire issue since the gauge read way past full. If it were the gauge it probably wouldn't read at all.

So after searching the message boards over the past year or two I hope this additional info helps someone else. The only thing I ever found was for a bad ground, bad gauge or bad sending unit...now you can add bend metal prong to the list. If I get time (and remember too ) I will post pictures of what I am talking about.

Don't know that I would have waited a year to fix that!

That's the general nature of electric faults - you are unlikely to just look up what happen to others, and find the exact answer. You may find a general direction, but your particular fault could be anywhere in the circuit path. It can take a bit of detective work.

Fuses, connectors and grounds are usually a good starting point, or back-probing with a meter to find where the signal/voltage disappears.

 

Just either never got around too it or when I did I couldn't find the issue. Plus I have a car for work so didn't drive it all that much over the last year.

i hope this is whats wrong with my 86 iroc a few of my guages dont function properly or at allmy fuel gauge pegged itself at the pump icon all the way at the top. tach reads at 4500 at idle voltage doesnt work either. any suggestions on the other gauges would be great.

 

MY PANEL CLUSTER LIGHTS WILL NOT WORK. MY SHIFTER AND VENT LIGHTS WORK NOW BUT TEMP GAUGE AND INTERIOR PANEL CLUSTER LIGHT DONT WHO FIXES PANEL CLUSTERS?
