The lights on the buttons in my steering wheel don't come on any more .Where do I start .
Is it all of the or just one of them. I don't know which model you have, but I'm thinking the light bulbs are not replaceable and you must replace the affected switch. In some cases you can work the switch out with a small flat bladed tool. If after you take the switch out, possibly the bulb can be replaced and or soldered in.
they all went out together . Its a dodge ram 2500 slt 2008
