Door sensor-draining battery

[werkenklasse]

Hey Guys,
Have a 2001 F350 CC 4x4 LWB SWB Auto Lariat. My dome lights are staying on after I lock the truck and the indicator says I have a door open. I know I don't have a door open but I have opened and closed each one several times to try to figure out which door is causing problems. Is there a door sensor that I can trip to see which one it is and if so how do I go about replacing it? Thanks.

Try spraying a bit of WD40 into the latches. This is a common problem.

yeah i second that opinion i have a 03 f250 kr and the doors did the same thing even when i was driving and as a matter of fact i came here for advice what i did was i used a degreaser first to clean all the crud out then used an industrial penetrating oil w-d40 is good but dries out, use something that wont like a spray grease works well for me

It works! Put some WD-40 and the indicator works normal again. Haven't had a problem with the lights coming on either. Thanks for the info.
