yes, they are supposed to light up. I assume your talking 01 and later? One of mine went out. I havnt gotten around to fixing it, but during research I found that some people go to radio shack and replace the LED's themselves. Let me know and i'll pull up some of the articles for you.
Thanks for the input, I was beginning to wonder if anyone had this problem. I tried to figure out how to access inside the switches to change a bulb, but could not for the life of me figure a way in. If you have some articles or can point me in the direction I would really appreciate it. Yes I have the 01 DXL. Thanks again
Huh?! I've got an '03 with all the steering wheel controls (mileage/odometer, stereo, driver settings computer, etc.), and not a single one of them lights up?! What gives????

I had one of my bulbs in the steering wheel control buttons go out on my 03 Yukon XL recently. I pulled out the whole switch assembly and then disassembled that...looks like there are two small bulbs that are soldered into the swtich PCB. I'm going to try to install a new one, will post results.
I also have one out in my radio head unit, any help there would be appreciated.
