Instrument panel question for 1991 D150

[TommyDodge]

The complete instrument panel on my 91 D150 quit working.
according to the owners manual there is a fuse for the panel that also has the key in the ignition and lights left on buzzer. The buzzer still works, but no gauge works and neither does the speedometer or odometer so I can't figure out what is up, I wouldn't think all the sending units for the voltmeter, gas gauge, temperature gauge and the oil pressure gauge and the speedomer and odometer would all quit working at once
Thanks in advance for any help on this

Instrument Panel Question for 1991 D150

I bought a box of new 5amp fuses and removed the old one which didn't look bad and replaced it with a new one and now everything is working ok
does anyone on here know how to reset the maintenance required lights on the panel above the heat/air controls, or would it be easier to pull the bulbs out?

the "maintenance required" box is located behind the glove box on top of the heater box / open glove box and then with both hands pull down and out on the very back edge / the BOX is "white'" and you have three choices as to what to do # 1 push the button on the side to reset it [ till it comes on again] # 2 remove the battery from the side of it and forget about it # 3 unplug it and throw it away and then forget about it

Instrument panel question for 1991 D150

There is a anti lock light on that panel that is on and I was wondering if the truck has anti-lock brakes? I didn't think that trucks had them until later. The date of manufacture is July 1991 which is late for a 91 truck
Thanks for all the help

Your truck has rear anti-lock brakes.
