My original intent for doing this was to install a set of white gauge backgrounds, but I misplaced them and couldn't do it! Oh well, they'll turn up sometime soon, and this is really easy!
Tools needed: small & medium phillips screwdriver, medium flat blade screwdriver, cleaning rag, q-tips and rubbing alcohol.
Cluster had dirt inside, and I got tired of looking at it. First thing to do was remove cluster from truck. Easy to do, remove the upper and lower column shroud from the steering wheel, remove two top screws that hold cluster to dash, pull the bottom out as these are only held in by two clips. You'll need to tug on it a little. Remove the speedo cable by pinching the knurled spot and pulling straight out, this is a little tricky since you don't have much room back there, and the short length of the speedo cable only allows about 3/4" of play. Than remove the electrical connectors. These are all one way connections and you can't plug them in the wrong spot.
Cluster out! Ready for cleaning!
These clusters don't use a PCB board, but rather a thin mylar like backing with copper "lines" sure there is a name for it and someone will correct me. Going to take this off and clean it too! You don't need to memorize the locations of all the lamps as they are interchangeable.
Remove the back housing of the cluster from the front, fairly easy to do, there are 4 plastic tongues along the top, and 2 on the bottom. You may want to be careful if yours is brittle. The polycarbonate cover is removed the same, it is held on by plastic tongues along all four sides, the bottom two can only be reached by the flat blade screwdriver.
now to remove the mylar board. Simple, but take your time. This is only held on by the plastic guide posts as well as the pressure from the electrical connectors. Take the q-tips and soak the ends in the rubbing alcohol and clean the electrical connectors as well as the copper from the mylar board.
This was a little tricky to get off. Both top sides of the mylar board feed through the cluster to the electrical connections on the face side. You need to disconnect this, lift the mylar board from the guide posts and feed it back through the cluster.
To clean the gauge faces, you can remove the faces and clean them or leave them in place, but be careful as the needles can bend.Simply clean all the parts and assembly is reverse!
