It's not a fuse , the SJB - smart junction box controls these lights ! This is fords body control module . If the Heater / A/C control panel ,hazard switch ,headlamp switch , message center switch all work, it is not a fuse . The gear shifter I would say the bulb is burnt out . The steering wheel lights could be out because of an open in the clock spring . The clock spring is a device inside the steering column under the steering wheel that keeps your horn , cruise control , radio buttons etc... connected electrically . How cars clock spring works
The radio doesn't from the buttons on the steering wheel ? The clock spring inside the steering column could have an open in the wiring ! The clock spring allows you to turn the wheel from full left to full right while keeping the horn an radio control buttons connected electrically with wires going down the steering column . Do you have a Air bag light lit on the dash ? How cars clock spring works
You must remove the steering wheel this means you must disarm the steering wheel airbag. To do this disconnect the battery negative cable while working on the car. Remove the **** shell plastic covers on the steering column the screws for them are on the underside they should be cross points, now remove the steering wheel nut and apply the puller you must purchase to the bolts holes and turn the jack screw in until the wheel pops free. After the steering wheel is off remove the clock spring ribbon contact drum under the steering wheel and then the switch just slides up and off once the clamp is released that holds it to the steering tube...
You have a defective part called a clock spring contact under the steering wheel, this contact is a coiled up simi rigid plastic ribbon with circuits embedded in it, after many years they l break and you loose the connection from the steering wheel controls (radio) and the Airbag. You must disarm the airbag on the steering wheel and remove it and replace the clock spring contact drum under the wheel, the cost is about $300.00
REMOVE HOTWIRE HORN OR PRESS REMOTE BUTTON LOCK CAR DOORS IF YOU HEAR CAR HORN BLOWS WHEN ACTIVATE CAR ALARM. HORN WORKING.MORE LIKELY THE AIRBAG AND HORN PAD NEED REPLACING.IF YOU GOING TO FIX. DISABLE AIRBAG IN THE STEERING WHEEL BEFORE REPLACING THE AIRBAG AND HORN PAD. TURN OFF RADIO.THEN DISCONNECT NEGATIVE BATTERY CABLE FOR 20 MINUTES BEFORE REMOVING AIRBAG IN STEERING WHEEL.THAT HORN PAD WITH AIRBAG IS NOT GOING TO BE CHEAP.
This is as a result of a short occurring most likely in the radio harness.
It happened me while working on a customers car. In my case checked all fuses and they all appeared fine, both those under the hood/bonnet and those underneath the steering wheel.
After studying the workshop electrical schemmatics for the car it appears that the clock, interior lights, central locking receiver and radio permanent live/battery are all on the one line.
In effect damage had occurred after the internal fuse panel, therefore all fuses were ok and supplying power across them, but at some point after there was a break in the wire.
However you DO NOT need to remove dash and or replace harnesses to rectify.
Look at the fuse panel underneath the steering wheel. Slot 18 (bottom RHS) and you will see in raised plastic 'BACK UP'. Inserting a 10A fuse here will restore the interior lights, radio, clock and your central locking.
There is a small plastic piece in the way which prevents a fuse going in. Simply use a thin pair of pliers, scissors or a screwdriver (or similar tool) to break this and all pieces of it away until you are able to insert the 10A mini blade fuse.
(I believe the fact this back up exists is because the designers of electrical system at mitsibushi realised it had shortcomings or this would be a potential problem - and included the back up for such an occurence)
