Dome lights only work in ON mode. 2008 Escape.

[Pepse]

Hello folks.  I searched for and found no answers to this problem.   This is a XLT.  Nothing fancy.  So as said the dome lights only come on in "ON" mode. When switched to Door nothing happens. No dome lights.  Also, the thumb wheel on the dash to turn on dome lights does Not work either.  The umber 9 fuse (interior lights) is good.  Any thoughts?

Does this do this when you open every door, even the lift gate?

If so, more than likely the Smart Junction Box (underneath the centre of the dash) has failed.

If you can verify that there is 12V on both sides of the fuse with it installed then the transistor that controls the interior lamp output from the SJB has probably failed.

Knottynuts,

I will look into the number 9 fuse as soon as I get out to my Studebaker to get my tester.

Thanks for the reply.

Knottynuts,

  Yes this happens with all doors and the liftgate.  I just checked the voltage at the fuse and I have 11.08 volts.  So, then it is apparently the SJB?

Almost definitely. The only thing you could do more is check for the signal right at the SJB from the jam switches input C2280C pin 2,3,14,15,or 16) and check the output to the dome light output (C2280A pin 9) while verifying your connectors/connection is ok.

If the inputs/output are ok then there is a wiring problem, possibly to the dome light (and cargo lamp).

Okay, but how do I access this SJB?

It's basically the fuse panel in the left side of the front passenger floor area. To access the entire unit you would have to take apart some of the center console area.
