Neither gauges are working, but, if I plug a scanner the gauges start working, any idea?
Stock car, no hacks?
fuses to cluster, there are 2 fuses.
the cluster has a simple self test mode, try that yet?
first?
2004 TJ,
the book is free
read chapter 8J for self test (IIRC push trip button key on)
if that fails 100% the fuses are blown.
the word is "Actuator test" in that chapter.
now the schematic, in chapter 8w, called wiring
page 40
fuse 26 PDC
and fuse 10 cab JB.
the cluster is really a computer.Display system)
when you jack the scan tool in, some power may leak form scan too to the display.
forget the scan tool, for now,
do the self test. first. if that fails, its lost power.

The gage is working because it is coming on sometimes. The oil pressure sending unit on the engine is starting to go. I would replace the oil pressure switch on the engine first.

A poor connection at the self docking connections of the cluster. Remove the trim across the top of the intrument panel. Remove the screws at the top of the cluster trim and remove the trim. Remove the cluster screws and cluster. Apply dielectric grease to the self docking connectors of the cluster and reinstall. This should take care of it.

IF YOU REMOVE INSTRUMENT CLUSTER AND UNPLUG IT,PLUG IT BACK IN AND UNPLUG IT AGAIN..DO THIS A FEW TIMES..IT SHOULD CLEAN OFF SLIGHT OXIDATION ON CONNECTOR TERMINALS..HAVE SEEN THIS BEFORE..I ALSO THINK REPAIR CONNECTORS AVAILABLE FROM DEALER

faulty cluster may have to replace it. try testing a junked unit if it works keep it.
