I just spoke to my bro who has a 98 Regal GS & he had the exact same problem. The circuit board for that display has a known problem with the resistors literally popping off the circuit board. They have to be replaced and new ones soldered back on. If you are not mechanically inclined for this task, then get a really good electronics person to do it. At a web site called regalgs.org they have the instructions to fix it. But, you'll have to sign up & blog until you get the solution. My bro says this is a very common failing for the Regal in those years. He was able to fix it for about $2 with new parts from Radio Shack. But understand he is a veteran Army electronics expert with 17 years in the service & knows exactly what to do, I don't. He told me & I remembered this issue he had with his car so I called him really fast to answer your question. He's quite the expert on Regals. He own two other Buicks as well. I hope I helped a bit.
