Default 1992 C4 Gauge Cluster no working

Hi everyone i am having issues with my C4 cluster not working properly.

I have the check gauges light on and my OIL pressure, OIL TEMP, and TEMP F gauges do not work.

The voltage gauge works and so does the rpm gauge. The LCD works fine too and does report engine temp on there.

I have taken it apart and tested the gauges individually with a power supply and they do move. The circuit board looks fine too and i checked all the traces on the board for the cluster and they have continuity. I cleaned the connectors also and they still do not work. I believe the gauge cluster is working and there is another issue. Anybody have any ideas what to check next?

I tried grounding the temp sensor connector as i read on another thread but the gauge still did not move as they mentioned it would.

any help will be appreciated Thanks

When I had problems with mine, I sent it to and had it repaired. Well worth the time and money to get it done. There's a wealth of info on the website also along with parts for those wishing to fix it themselves.

If you determine your BCM/CCM is at fault, I have a 92/93 CCM I used as a backup that is available and for sale.
