Hello Customer


I'm Chris, Thanks for coming to Just Answer, I am going to do my very best to provide an answer you can Hit Accept on in a timely matter.


Does the dome light ever come on while you in the car uncommaded?

Does the door ajar light in the instrument cluster work and does it ever come on while driving?


Customer: replied 7 years ago.
Not that I am aware of Chris. Car sits under an covered carport. Could not see anything wet in the car or under the hood. Appears to be no corrosion under the hood.

Since your not getting this concern while driving the vehicle then there is no way to know if this is a door ajar sensor or Lightning control module causing this concern. You are going to need to get the LCM scanned for trouble codes to see where the failure lies. If you click here you will see how I am basing my answer from the ford diagnostic steps
