Interior lights stay on and all power windows inop

Have you recently done any work in the doors? It sounds like a short or connection issue with your door lock harness inside your door.

Does the van have remote keyless entry (RKE) system ?
Interior Lighting System Description
Vehicles with the optional remote keyless entry (RKE) system have interior lighting controlled by the body control module (BCM).
This vehicle uses a delayed interior lighting system.
The system functions as follows:
• The dome lamps will illuminate when any door is opened.
• The dome lamps will remain on for 20 seconds after the last door is closed.
• The delay is canceled and the dome lamps will go out when the ignition switch is turned to the ON position.
• The illuminated entry function will not operate when the dome lamp defeat switch is in the OFF position.
• The interior lighting system is protected from battery rundown by the retained accessory power (RAP) system. The RAP system functions by shutting down interior lights after 10 minutes (when ignition is OFF).

Interior Lights Circuit Description
When the interior lamps circuits are closed/enabled, the courtesy lamp relay is activated by the two following coil circuits:
• CKT 690 (GRY/BLK) which is the courtesy lamp enable output of the body control module (BCM) driving the coil side of the relay.
• CKT 1732 (ORN) which is the coil output side of the relay going to the potential grounding switches/sources.
When the courtesy lamp relay is enabled, CKT 156 (WHT) (courtesy lamp output) is enabled by the closed contact at the relay and then grounded by CKT 750 (BLK) at G110.
Some of these circuits can also be activated with the headlamp and panel dimmer switch. When this happens, the coil output side of the inadvertent power relay is grounded to the body control module (BCM) via CKT 1393 (DK BLU)
CKT 40 (ORN) from the courtesy fuse drives both input sides of the inadvertent power relay. When the contact is pulled closed, CKT 1732 (ORN) is supplied power, thus driving any lamps/circuits attached that circuit and providing ground.
The body control module (BCM) also monitors the following four door inputs:
• CKT 49 (DK BLU) -- LH door jamb switch input
• CKT 54 (ORN) -- RH door jamb switch input
• CKT 775 (PNK) -- Side door jamb switch input
• CKT 656 (YEL) -- Rear door jamb switch input/liftgate strut switch input (depending on option content)
When the doors are closed, the body control module (BCM) is in a floating state of 0-2 volts. When the doors are opened, the courtesy lamp relay is activated, sending power to the courtesy lamps.
The headlamp and panel dimmer switch also activates the following interior courtesy lamps when the switch is placed in the PARK or HEADLAMP ON positions:
• RF power window switch
• RH power door lock switch
• LH power window switch
• LH power door lock switch
• LH outside rearview mirror control switch
• Rear radio control head
The dome lamps can be disabled by closing the dome lamp defeat switch located on the headlamp and panel dimmer switch.

Value(s)
Yes
No
Important: Verify functional bulbs before beginning diagnostic procedure.
1
Did you perform the Lighting Diagnostic System Check?
--
YES - Go to Step 2
NO - Go to Diagnostic System Check - Lighting Systems
2
Are all of the courtesy/dome lamps inoperative?
--
YES - Go to Step 6
NO - Go to Step 3
3
Activate courtesy/dome lamps
With DMM, check for battery voltage from inoperative lamp CKT 1732 (ORN) to ground
Is battery voltage present?
B+
YES - Go to Step 4
NO - Go to Step 5
4
Repair open in CKT 156 (WHT) between inoperative lamp assemply and S214.
Is the repair complete?
--
NO - Go to Step 10
--
5
Repair open in CKT 1732 (ORN) between inoperative lamp assemply and one of the following splices:
• S258
• S301
Is the repair complete?

Go to Step 10
--
6
Turn the courtesy lamp switch to the ON position
Check for battery voltage at BCM C2 cavity B12.
Is battery voltage present?
B+
Go to Step 7
Go to Diagnostic System Check - Body Control System in Body Control Systems
7
Verify continuity of the following three circuits with DMM:
• CKT 1732 (ORN) between courtesy lamp relay and body control module
• CKT 156 (WHT) between courtesy lamp relay and S214
• CKT 750 (BLK) between courtesy lamp relay and S206
Are all of the circuits functional?
--
Go to Step 8
Go to Step 9
8
Replace courtesy lamp relay.
Is repair complete?

Operate the system in order to verify the repair.
Did you correct the condition?
--
System OK
Go to Step 2

Have you tried checking the dimmer switch for your instrument panel? I believe if the switch is slid all the way up it will cause the interior lights to stay on. Hope this helps.

sounds like a blown relay and also a blown fuse or two, check the relays under the bonnet and under the dash, you will surely find a broken/worn/burnt out one, replace it (not sure which one it is but they renge from £3/$5 to about £12 - $25 then replace the fuses, if there is no bad relay then just replace any blown fuses - hopefully it's just a worn out relay and not something wrong with the windows or locks that blew the relay in the first place -

CHECK THE WIRING BETWEEN DRIVER'S FRONT DOOR AND DOOR POST..HAVE SEEN BROKEN WIRES IN THIS AREA FAIRLY OFTEN..TRY TO KEEP WIRING REPAIRS OUT OF THIS AREA..WILL ONLY BREAK AGAIN..REPAIR CLOSE TO CONNECTORS,REPLACING WHOLE WIRE IN BETWEEN

I had this same problem but no sunroof on mine. there is a bundle of wires that goes into the door and if the power wire breaks and the power window lockout was pushed when it happens no windows work and the dome lights stay on on mine it happened on the drivers side it was an easy fix i took the door panel off and unpluged the harnes and pulled it through the inside of the jeep and spliced the wire back together and it has been working since.

you have a broken wire in door to body wiring loom repair this and all will be back to normal

Sounds like a fuse issue. check your panel for popped accessory fuse.

the overhead light issue may be the door close switch

Common issue with the early 2000 series Jeep is the window/door lock control on driver side goes dead when the thick guage wires in door become brittle and break from continually opening and closing the door. Had both the ground and hot wires break over the years and both are fixed by making a simple jumper connection with a little extra length added.

Fixing is relativly easy if you know how to crimp wire connectors otherwise you my want someone more experience to help.
Open door, pull back rubber sheath and expose wire harness, unclip the plastic retaining clip and pull out wire harness and located which wire has broken (typically the thick black or orange wire) . Prepare both ends for crimp connector and make a jumper with small peice of heavy guage wire and crimp connector of either end then connect each end to either side of broken wire, tuck wires back in, replace retaining clip and rubber sheath.

You can find videos on youtube showing how to fix

Hi all,
suppose you have worked out your little problem. I have just been experiencing the same thing with my 2004 GC ltd. Windows, mirrors, etc not working and interior light staying on. Took it to the shop and they re soldered the wire (behind the door panel) that had come off. Cheap problem really.
