The interior lights won't shut off. I have to

That is normal operation, as long as the door is open the door ajar switch senses that and keeps the interior light(s) on.

look for main fuse panel under hood, there should be a charging circuit fuse check it

how odd ,I would check for a fuse link(under the hood)
or the ign. switch.
Make sure the battery terminals are clean and tight,jeep
seems to like lots of battery,any loss of voltage makes wierd
troubles ,alarms go off for no reason ,ect..

This can be caused by a door or trunk being ajar, be sure you shut all doors firmly, if there is still no resolve check by shutting all doors then open one up and press the button (if any) on the inside of the door jam and see if it is broken or the light goes off.

That is a really good question....what category did you post it under?

Thanks for choosing FixYa and welcome. Trunk lights can be tricky. Make sure it is not on. Check for any lights in the glovebox or under the hood, dome lights, even the radio. If your battery is draining, check the wires, battery post, and terminals. They may need cleaned. May need a new battery if it continues to not hold a charge.

YOU MAY HAVE A BAD DOOR AJAR SWITCH. HOWEVER, YO HAVE A TIMER THAT SHUTS OFF THE INTERIOR LIGHTS AFTER 300 MINUTES. IT'S CALLED A BATTERY SAVER FEATURE. TEST IT OUT.

THE EXTENDED CRANK MAY BE A CHECK VALVE IN THE FUEL PUMP IN THE TANK, ALLOWING PRESSURE TO DROP WHEN YOU TURN THE ENGINE OFF.
OR A BAD FUEL PRESSURE REGULATOR ON THE ENGIEN FUEL RAIL.

TRY THIS TEST, TURN KEY TO "ON" POSITION, WAIT 5 SECONDS, SHUT OFF KEY FOR 30 SECONDS. TURN KEY ON, WAIT 5 SECONDS, THEN START ENGINE. IF IT STARTS RIGHT UP, YOU ARE LOSING FUEL PRESSURE WITH ENGINE OFF.

THIS BUILDS UP PRESSURE IF IT DROPPED DURING SHUT DOWN.
REPORT TEST RESULTS.

PLEAE RATE, THANKS

Could be several things. The battery or alternator can be tested at most of your local parts store. I would start with those probably battery first then alternator as batterys are less expensive and earier to install. What ever u decide to do i would make sure to get both checked to avoid burning up a new battery if it is the alternator as well as the battery.

Check your battery terminals make sure they are clean and corrosion free.
Also check all ...A-L-L courtesy lights in your car. there are some ceiling mounted lights that are passenger operated and may be on... Also check your glove compartment and consoles for lights.
Also check for charger cords... These have indicator lights and sometimes can drain the batt as well.
Also, under the hood, is a gravity activated lamp . Open the hood and make sure that it's going off and staying off as the hood closes...
Let me know if you find anything...

If you are starting with a fresh battery and it drains down overnight or ina day or so.First make sure you alternator is sufficiently charging.Then make sure all components are switched off,including any interior lights (from doors being open)and hood lights (from hood being up).Take your ground cable loose from the battery and place a 12volt test light between the cable and battery terminal.You should have no, to very dim light.If you have a bright light,then start pulling fuses out one by one.(take one out and then replace it before you remove another)When your test light goes out,see what component the fuse is for that made the test light go out.Then check that circuit or component for short.Good Luck!!!
