I just replaced the lights on steering wheel controls for my 98 grand prix.
If anyone is interested in having yours repaired, I could do the same for yours. I also replaced two of the microswitches also, that requires me modifying it slightly though.

I have a 97 with a bad volume micro-switch. I've been looking for replacements but haven't been able to find any other than dealer.

Still interested in doing some repair?

If I lived closer to Maryland, I'd let you look at my 98 GTX. But I will get to it soon.
Thanks
