Door ajar light staying on
 

What's going on everybody have a 04 Intimidator love it running very strong but I have an issue with my door ajar light coming on I had an issue couple days ago I was driving to work and the door ajar flashed and the chime started chime in light came on my dome light on my courtesy lights went off started going on and then went off again spray some WD-40 in the latch it seemed to help the problem for like 5 hours and then the lights stayed on constantly now when I put my vehicle in drive my light will still stay on but the dome lights go off but when I put the car in park my dome light stay on and a door ajar light is on constantly it's not flashing I would I think it wouldn't be the BCM the body control module because of body control module functions of a lot of other things I'm having no issues with anything else that's the only issue that I'm having my door ajar light is staying on constant any help would be great I did do a video of it so I could post it if you all want to see it I'm thinking it's the door latch inside the door
