Digital Speedo Needs Help!

I have a 94 Caprice Wagon with the digital speedo. Today, the speedo went dim and the turn signal indicators stopped illuminating. When I say dim, I mean dim--not dark. I can still see the readout unless the sun is in my face, but it is incredibly tough to see. I had a brief moment of full brightness a few minutes ago when I pulled out of my driveway but the speedo dimmed immediately. My turn signals are working just fine--the indicators just don't illuminate.

Who has ideas?

Thank you, sir. I will give that a try as soon as it isn't 100 degrees outside.
