Customer Question

I have a 2007 Ford S-Max Titanium. I recently tried replacing the interior (middle) festoon bulb with an LED variant (the key was in the ignition) and on replacing the bulb, the interior lights now do not work nor do the electric windows.
Strange thing is that front passenger window works with individual control but not from drivers door panel controls (for either front or back).
Everything else works.
Any ideas?

Hi there ,good evening to you
Ok I have has s look at the diagram and suspect you have blown a fuse in the BCMii (this is the fuse box located in the passengers footwell under the glove
Can you inspect fuse 7 ,9, 14 & 17
I suspect one of these will be blown
these fuses are all linked to the same system eg interior lights etc
There is 2 different fuse box designs so if you can check these first and let me know

According to the manual, the central fuse box design is E75527.

I have looked in said manual and the fuses you mention (F7, F9, F14 & F17) are Steering Wheel Module, Main Beam, Front Screen Washer and Interior Lamps respectively.

Are these what you expected?
