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.http://www.fixkick.com/Jeeps/cluster-hack.html
the used head will not work it has the wrong VIN stored inside it
other tricks are here, including ASD stalls. and free books.http://www.fixkick.com/Jeeps/jeeps.html
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
and low washer fluid
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.
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.
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.
