Ok at first I thought it was just the fuel not working because it was stuck. Well today I noticed my temp and spedo gauges also aren't working. The light comes on if I turn my headlights on but gauges still wont budge.1988 4wd 3.0 truck

The temp gauge could be the wires/connectors, the gauge, or the sender.

The speedo is driven by a cable on an 88. The cable might not be the problem though. Does the odometer still work? Check for trouble codes, if there aren't any then the cable isn't busted.

I have the same problem with the fuel gauge sticking sometimes too on my 88.

odometer still works to the best of my knowledge ( havent driven the truck besides in my drive way) but it looks like it has moved. Is there some type of fuse that controls the dash?

These 4 fuses are for the gauge cluster according to the 88 FSM:


Those are in the fusebox in the driver's side kick panel(lid for it below).
