what would cause my dash power to all go out?
dash power out on 1999 Oldsmobile Aurora
If the engine runs then chances are that the fuses that power the dash are OK. To be sure try checking the fuses in the instrument panel fuse box. If the fuses are OK the gauges cluster will need to come out to check for proper power and ground to the cluster. If those checks are OK then you may have an internal fault with the cluster.
