I have been complaining about my instrument cluster dash lights since I had my car (approx 2yrs), I finally asked a mechanic to fix this problem while he did other repair work on my car.
He took the entire cluster out, cleaned everything (prism, all pastic parts, etc), replaced both bulbs w/OEM bulbs (3w I think-mechanic only uses OEM parts), the sockets they go into, and solered (spelling?) in a new ground wire.
Now my dash is TOO BRIGHT! hehehe. Just kidding. I love it. Feels like I'm in a new car. Everythig works in my dash (RPM & clock stopped was not working prior to removing the cluster) except the economy guage.
Hope this experience will help others.
