Kia Troubleshooting Questions? Ask a Mechanic
Hi. Have you tried opening a door other than the drivers to see if the dome lamp will come on?
Ok. I know of the diode concern you are looking for, but that was on much older sorrentos, like 2004. I am going to review the wiring diagram and check for any messages from kia. Give me one second.
Do you have power tailgate?
There are no messages or bulletins from KIA on this issue. The interior fuse panel has the software built in which controls the dome lamps coming on when the door open signal is sent to it. The door open signal appears to be working, since the sill plate lights up when the door is open. The first thing you need to check will be the fuses. In the interior fuse panel, check the fuse INTERIOR LAMPS (10amp), MODULE 3 (10amp), and MEMORY (10amp). If those fuses are good, then the next step will involve using a test light and checking for power from the fuse panel to the interior dome lamp assembly and possibly some other locations, to find why power is not being applied when the door is open.
