Have Jeep Questions? Ask a Jeep Repair Expert for Answers
do you have the vin so I can pull a wiring diagram, all our wiring diagrams are vin specific,also are you referring to the INSTRUMENT CLUSTER lights?
do the heat and a/c back lights operate?
you will need a test light and the ability to use it along with a digital volt/ohm meter
what is your skill level?
ok can you use a test light and can you remove the instrument cluster for testing?
I still need the vin for a wiring diagram
if your radio lights work that is a strong indication there is a wiring issue NOT a relay
give me a minute to look up the wiring for the dash lights
OK you have a pretty basic wrangler no a/c and a decent factory radio, and my favorite color red looks so good on a jeep, the heater controls SHOULD have lights that light up when you put on the headlamps the feed wire for these is spliced together with the radio lights and the instrument cluster lights do you have the factory radio still or is it an aftermarket one?
I have a wiring diagram I will send you and you WILL definitely need a test lamp and digital ohm meter to determine if you lost power or ground
a jumper wire to provide power to the circuit will be helpful BUT all the power for the dash lights and back lighting originates inside the instrument cluster so you MAY be looking at a failed cluster
and lastly does the trip reset button work?
there is a fuse box inside the jeep behind the glove box
fuse 10 feeds the instrument cluster lamps see if it has blown remember BEHIND the glove box
the glove box should drop out easily look for 2 stops and squeeze them together and then pull out the glove box
ok you will need to do some testing now do you think you and your partner can read and follow a wiring diagram? there is 1 wire that feeds all the back lights
ok before you tear into everything just check each of the fuses in that fuse box for any that are blown if they are all ok the easiest thing to pull out looks like the heater control, there will be an ORANGE (small gauge) wire on one of the connectors that wire should have POWER with the headlamps ON if it does then the instrument cluster is sending out power, next you will need an ohm meter to check the small BLACK wire in the same connector as the ORANGE wire this wire should show continuity to ground if not the lights will never come on you need power AND ground to make a light operate.
here is a link to the back lighting for your jeep the extra switches are for options you do not have, please download and print it out and ask me any questions you have about it, it is in WORD format
I also have to log off for the night its pouring here in Connecticut and there are major thunderstorms in the area, I will be logged back on tomorrow after I get off work, FYI I do check my emails throughout the day BUT can only respond on my breaks, I as most of the experts still work in the field
