Door switch: Make sure the door switch is functioning properly and is not stuck in the "on" position. The door switch is located on the door jamb and is responsible for turning the dome lights on and off when the door is opened and closed.
Wiring: Check the wiring between the door switch and the dome light. Make sure there are no broken or frayed wires.
Fuse: The dome light circuit may be protected by a fuse. Check the fuse panel for any blown fuses related to the dome lights.
Dome light assembly: The dome light assembly itself may be faulty. In this case, you may need to replace the assembly.
It's also worth noting that some PT Cruiser models have a feature that keeps the dome light on for a short period of time after the door is closed. This is to allow you to find your way in the dark if you need to retrieve something from the car. If this is the case, the dome light should turn off after a few minutes. If it does not, there may be an issue as described above.
