Got in the car today, pressed the heated steering wheel button, the light comes on and I forget about it. About 5 minutes down the road, I'm like "Hey, where's my heat?" I click the button off/on, still no heat. At a stop light, I turn the car off and back on again, hit the button. it lights up, but still no heat. If it was a fuse, the button wouldn't light up would it?
