How do you replace the light in the switches on the steering wheel

Before you start replacing parts ,need a little more information . Maybe able to save you some time an money . Does the horn work when you push the horn button , does the air bag light stay lit in the instrument cluster ? The button lights for the bottons on the steering wheel are lit by the BCM - body control module . Interior Lamps Dimming
The second group includes lamps which may be dimmed. This group may use a combination of vacuum fluorescent (VF) illumination and incandescent lamps.
When the ignition switch is turned to the RUN position, the radio's vacuum fluorescent (VF) displays turn on at maximum brightness. When the park lamps are on, all incandescent back lighting turn on at the dimming level indicated by the I/P dimmer switch. At the same time all vacuum fluorescent (VF) displays dim to match the indicated dimming level. The panel dimmer switch potentiometer is an input to the BCM. When the driver selects a dimming setting by moving the I/P dimming switch potentiometer, all incandescent back lighting lamps are provided with a specific voltage. When the I/P dimmer switch is moved from MIN to MAX, all vacuum fluorescent (VF) displays, as well as all incandescent back lighting respond from minimum intensity to maximum brightness in response to the I/P dimmer switch.
The following switches and components have back lighting when the park lamps are on:
• The instrument panel cluster (IPC)
• Radio, front and rear
• Window and heated seat switches
• Garage door opener switch
• Selectable ride switch
• Roof beacon switch
• Power take off (PTO) switch
• Headlamp leveling switch
• Rear wheel steering mode select switch
• HVAC control assembly
• Headlamp and panel dimmer switch
• Transfer case shift control switch
• PSIR disable switch
• PRNDL lamps
• Traction control switch
• Steering wheel control switches
• Fog lamp switches

Could be the clock spring inside the steering coulmn ,under the steering wheel if horn doesn't work ,air bag light lit etc...

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

Hi Shannon, befor you dive in and replace the indicator switch I would suggest you check the flasher unit. To replace the indicator switch you will need to remove the steering wheel (this usually means using a puller) Don't forget to punch match marks on the steering wheel and the column which must be aligned when assembling. Remove the steering wheel center cover. then the covers on the steering column Removed the screws (usually four) holding the stalk switch. don't forget to disconnect the battery and the wiring connection to the stalk switch. After replacing the assembly is opposite.to dismantling. Regards John

for safety remove the battery terminal of the positive,remove the horn switch in the steering wheel just pull it out,u can see the bolt on the steering wheel remove the bolt and the steering wheel also.find the four screw in the combinition switch remove the screw and remove the steering column cover to remove the socket connector. pull it out the signal light switch.

Installation Procedure

there is no bulb you need to replace the switch in the steering wheel

The switch has to be replaced, the bulbs are not serviced seperately. On some of the vehicles, you could pull the the switch out far enough to access the connector and change it from the front, but be careful, if there is not enough slack in the harness, the steering wheel has to come off, along with the rear cover on the wheel, to get enough slack in the harness to remove the switches. This was a design change around 2004 or 2005.

the switches in the steering wheel do not have bulbs, the switches have LED which lights up.
so if the lights in the switches are not working you'll need to replace the switches.

steering wheel controls? you have to replace the switch bulbs are not replaceable. switchs are not expensive I think all of them are like $75
