Ray 2000 C5 FRC

Drove my 2000 C5 early this morning and had no dash lights, and no parking lights. Headlights and turn signal worked just fine. Also, radio station display (but not the control buttons) and DIC worked as usual. Read a bunch of threads related to this issue and for my car the Steering column multi-funtional signal switch was at fault. I took it apart the multi-functional signal switch (GM Part number 26075870) and located the contacts that power the lights. The contacts were somewhat pitted. A light cleaning of these contacts and reassembly fixed the problem but just so I don't more future gremlin's I place an order wit GM Parts $229.99.
Just wanted to share this finding in case others C5's begin having similar issues.

That is a great title for the issue and may help others in the future. I hate bad titles like "Help" with no info which means no one can search and find a potential solution for a problem that may actually be the same.

Good job, Mr. Sam

Is that you racing?

My first guess would be that the MULTIFUNCTION SWITCH on the column is bad. I will have to look in the repair manual to see what fuse controls that function/s

yes, it was at Heartland Park in Topeka, Kansas.

Thanks for your post Ray, I too appreciate the title for easy searching. This exact issue just happened to me last night. Everything on the dash works, then you flip on the headlights and everything goes dark, but the dash computer still notifies you of tire pressure issues, low fuel, etc. so it's clearly working. Turn off the headlights, the dials all light up, the odometer display comes back, and the radio display lights back up.

I'm a novice when it comes to electrical issues. Do you have a fairly comprehensive procedure for how you fixed the issue? It sounds like is was fairly easy to fix, but any help would be appreciated.
