Barney Eaton Posted March 21, 2002 Share Posted March 21, 2002 You must remove the bezel around the instrument cluster. You will find a Torx head screw at the top of the right and left vents. There are two more at the top of the instrument cluster..above the speedometer.<BR>With the four screws removed, use some sort of a hooked tool and pull straight out ...work your way around the bezel.<P>With that removed you can get to anything on the dash. Cleaning the contacts may be all that is required, but I have completely disassembled the units and sprayed contact cleaner under the buttons on one stubborn unit.
