Question about 1998 Jeep Cherokee
98 cherokee, interior and door courtesy lights stay on when ignition is in the off position, but turn off when on and responds with opening and closing the doors...I'v checked all the switches in the doors, all work correctly, but still I am puzzled on why the lights remain on...I'v been told by the dealership they can ''look at it'' for a nice $120 but they arent sure on a sure fix, they recommended I ''remove the fuses.'' When I did remove the courtesy light fuse, the door valets were still on so I removed both of those bulbs...I dont know what to do
There is a setting for that in the electronic info center. use the menu button to cycle through options displayed on instrument panel near the speedometer

The interior lamp switch is in the ON position.
The keyless entry transmitter unlocks the doors (illuminated entry).
When the key is removed from the ignition switch with all of the doors closed, the courtesy lights light for approximately 25 seconds before fading out.
Battery positive voltage (B+) is applied at all times through the IP fuse block CTSY LP/PWR MIR fuse 6A via CKT 640 (ORN) through the body control module (MALL) to the courtesy lights via CKT 1732 (ORN). The MALL provides a ground through CKT 156 (WHT) for the courtesy lights under the following conditions:
The MALL receives an input from a door being opened.
The MALL receives an input from the interior lamp being turned ON.
The MALL receives an input from the doors being unlocked using the keyless entry transmitter.
The courtesy lamps then light.
When the courtesy lights are activated by opening and closing a door, the courtesy lights will remain on for approximately 25 seconds before fading out after all of the doors are closed. If the ignition switch is turned to START or RUN within the 25 seconds, the lights immediately begin to fade out. If a door is left open, the MALL removes battery positive voltage (B+) to the courtesy lights after 10 minutes. When the courtesy lights are activated by the interior lamp switch, the lights remain on as long as the interior lamp switch is in the ON position. When the courtesy lights are activated by unlocking the doors using the keyless entry transmitter, the lights remain on for approximately 40 seconds. If the doors are locked using the keyless entry transmitter within the 40 seconds, the lights immediately begin to fade out.
