The dashboard lights are not working what is the problem

Check the bulbs & connections in the dashboard, also see if there is a fuse for instrument lights

Piggybacked 99 XJ from 2014 DEC. ok. no biggie.
but what car, same? XJ up to 2001?
op my guess he blew fuse 9 or 16
i bet the self test failed with the OP's car.
but lets talk your car, is it a 99 XJ?
the FSM covers this.
here is the full answer here. see instrument pages, read.

1999 XJ? facts on head,
pdc fuse 16 blown?
cab fuse 9 blown?
self test fails.?
now the hard wired warn LAMPS just this one year 99
seat belts
and low washer fluid
ABS fail.
brake warn. or hand brake engaged
chime inputs. hard wired.
tURNS (L/r) active and high beam.
illumination (back ground glows) works, hard wired TOO.
DEAD LIST.
all else will be dead if COMMs are lost or fuses out. depends on which fuse is dead, if both blown all warns dead and gauges.
meters all dead. with loss of comm and some warns below.
cel dead.
upshift dead
low fuel dead or stuck (stuck on or off is still dead)

the photo below shows why meters die
when comm LINK dies. or 12v power to head.

if all your dashboard lights are not working, locate the fuse box... one of its fuses might be busted. replace with the same ampere. ^_^

how about interior lights ? and backup lights are they working ? sometimes they are all on same fuse or relay

All tho the headlights are working do the side lights work also worth checking the dashboard dimmer switch

check your fuses in fuse box,you may find that running lights & dashboard lights are on a separate fuse to the headlights......hope this helps....cheers

Lights? more than one? It is extremely improbable that many lights burned at the same time. Jiggle the dashboard dimmer wheel (used for light attenuation adjustment) to see if the lights come back to life. Dimmers, being rheostats, have the nasty habit of burning spots, so they work only at a different location than the burnt spot. Many burnt dashboard lights might be an indication that they got too much voltage. ( Bad voltage regulator). Dashboard lights are placed in the rear of the assembly, and screw right into it. Dashboard must be taken out, and it isnt simple. Purchase a full set of dashboard lights at the car dealer before taking down the dashboard, because you dont want to find out that you dont have the proper bulbs, and the whole dashboard already disassembled.

CHECK YOUR FUSE ON DASHBOARD LIGHT

Check Fuse #6 15 amp under dash in fuse box also check fuse #4 10 amp both run dash and tail lights
