hi... mine is a 2007 F150 Super Cab Fx4.
i have gremlins in the bed light. it comes on randomly when ever it feels like it.
it is much easier to notice at night.
the wiring diagram i have shows it to be tied to the inside dome light but the dome lights do not light with it.
frequently, if i start the truck and run it a few minutes, the light seems to reset and behave normally.?
is there a switch in this circuit i should look for? could it be in the ignition key switch itself?

any ideas will be helpful. currently i carry a small wrench in my pocket and when it turns on,
i just disconnect the battery until the next time i need the truck.

thx in advance..

Dave

 

1. Scab for the win!!

really? u want pics of a bed light on and/or off? i am questioning the wiring. that is all hidden in the body.
what exactly would u have me offer u pics of?

 

do you have your dome light switched off manually by its switch (on the dome light itself)? if it is set on the middle/automatic setting does it then go on/off in tandem with the cargo light ?


i have an issue with phantom dome light on/off. it only occurs during first few minutes of driving. i can’t orove it, but believe it may be due to partially failing cluster (i also have phantom brake light warning on cluster)

 

check the roller switch left of the steering wheel.
