After having my truck for several years I finally plan to put in a new circuit board. The current one has not worked since getting the truck in 06 so I have the needed gages mounted under the dash. Would like to clean things up if possible. If anyone has done this can you tell me how long it takes, this is my daily driver so I have the weekends to get it done.
Thanks,

Since this is your first PCB swap, allow two plus hours to R&I the cluster, strip it down, clean it and reassemble. While you are there, replace all of the 194 dash bulbs or upgrade to LEDs. Burnish the gauge contact clips and bump their tension slightly with a pair of small needle nose pliers. Smear the contact clips with a sparing amount of antioxidant or dielectric grease to help manage oxidation of their connections with the PCB. Probably would be prudent to snap a few front and rear images of the cluster with the lens and mask removed. Manage all of the small screws and clips using an empty egg carton or partitioned parts tray of some sort. Because of its age, the plastic housing maybe somewhat brittle, so handle it gently and don't overtighten screws. If the truck has an automatic transmission, you should also smear a little white lithium grease on the 6" gear indicator cable where it passes over the plastic boss of the cluster to engage the steering column shroud. If the cable has sawed into the boss, carefully fill the grooves with epoxy.
