DIC issue
Not much action in the Electrical section so I thought I'd try here. The display part of my DIC works but none of the buttons have any effect. I tried using dielectric grease on the connector but that didn't help.
Any ideas on what to try?

Do the lights inside the buttons come on when you turn the lights on? Sounds like the harness that plugs into the buttons isn't plugged in or loose.

You should not use dielectric grease on these types of connectors. This is generally reserved for connectors that are exposed to moisture (underhood, outside body, etc). This will not help "make" a connection where one doesn't exist.
If none of the buttons work, you may have a bad ground. These buttons work by grounding various inputs on the instrument cluster. This circuit ultimately grounds at a splice pack on the driver side, behind the trim cover that goes around the hood release handle. It is bolted to the body and looks like a small black module. Ground problems are relatively uncommon on the 2000+ Bonneville because GM became much smarter about where they are located. The ground wire also runs through one of the two large, 40 cavity connectors behind the knee bolster in front of the steering column. You may want to make sure nothing was disturbed here.
You may also want to remove your instrument cluster and re-seat it making sure it is fully engaged in the dash. You may have a defective cluster. There is a way to clean the connectors that plug into the cluster, but I'm not convinced this is the problem. I would be if it was just one or two switches and the problem was intermittent.

Thanks for the replies. All of the display works and receives external inputs such as a door is open. However, last year I did remove the cluster to replace various burned out lights so perhaps I didn't get everything plugged back in.
Good information on dielectric grease as I wasn't sure about when you should use it.

Several people on this forum have had the dealer replace the DIC control panel...including myself.
The buttoms seem to just stop working, but the info from the car still shows up fine.

Bingo. I tried cleaning up the ground behind the hood release and no go but when I removed the panel and sanded the pins, all is now good.

I cleaned the ones in button cluster. Sanding was about the only practical way to do it since they are quite small and in a confined area where an eraser couldn't get to.
At any rate, I'm very thankful for the help and glad to have things working again.
