The only light working - Check engine light, rest dead as a stone. Truck otherwise starts, runs just fine. My cluster has DIC (driver information center), nothing works. Done some research, went to the dealer who was kind enough to reveal to me what local electronics shop they use to have these things fixed (York electronics- I am in Calgary AB Canada). Rodie is absolutely right, plenty places to get help with this hardware, just look them up on the NET.
Now good news, got ready to pull the panel out, disconnected battery for a few minutes to deenergise SRS. Barely started on bolster knee panel, needed to move the truck off the driveway. Reconnected battery to start the thing, AND panel rebooted like a Christmas tree computer. Did not even loose any memory, like odometer, seat and mirror positions etc. Sure made my day easier to get at the leaky front diff.
