There is no replaceable bulb in the illuminated switches on a steering wheel. There is no room inside the button for a bulb, and such a bulb would create so much heat, that it would melt the assembly The illumination LED is integrated into the switch circuitry. The only way to fix it is to relace the switch assembly.
You don't. Junk the car.
There are a series of wires that run from the steering wheel controls to the radio. An electronic circuit could be used, to combine several controls into fewer wires.
The cruise and radio switches do not share a common fuse.
your steering wheel radio controls are bad disconnect and your radio will come on.
My 1989 has them. I love this feature.
You need to buy and replace the switch. The switch is removed bu using a small flathead screwdirver, and simply prying it out of its hole on the steering wheel. Disconnect the wires, connect to the new switch and replace the switch in it's hole.
I believe the only way to fix this would be to replace the steering wheel with one from from a junker car. I don't think the controls are available to purchase individually and you would need to take the wheel apart to replace them in any case. Do what I did with my Bonny, live with it (much cheaper)
I recently replaced the factory radio in my 1999 EB Explorer and, while the new radio had a CD player in it, I lost the use of the 6 CD changer in the armrest. Also, if you have steering wheel controls or rear seat controls, you may need to also install an add on, assuming the radio has an infrared remote control, to enable these controls. I also did this and it works reasonably well.I used Crutchfield and they are very helpful in answering questions you may have - you should try that email@example.com
You have to replace the whole button.
It doesn't control anything. It is the connection for the cruise switches, horn switch, radio controls(if equipped) and airbag that allow the steering wheel to turn and there to still be a connection.
From new they would have been controls for the radio. Volume, Station, Cd/Radio, etc. I
