Hi I recently got a 86 Isuzu Trooper and I'm confused because the cluster of gauges in the center for temperature oil pressure and fuel gage do not work at all but the lights on them do work when I turn the headlights on. It has no blown fuses. The low light gas gauge does work and turns off properly runs fine no check engine light or oil pressure light or anything comes on the dashboard unless it is off with just the key in the on position
