My heated steering wheel is not always working in my 2013 LTZ burb. Every now and then when I press the button, the LED Illuminator will flash quickly but not stay on. Most of the time the light won’t even come on. And every once in a great while it works, but that’s a rarity. I read up on it and saw that this is not really an uncommon issue with these trucks. How do I properly fix it?
