Hey guys, need some serious help... I was revving my engine on my 2008 Silverado and heard what sounded like a fuse popping from the dash and now my shift indicator doesn't show which gear I'm in and my reverse lights do not illuminate. My odometer works fine, and the gears are illuminated, just not the square that highlights which gear I'm in. It's not even highlighting the P when in Park. It's just gone. The truck cranks and drives fine other than that, you just have to feel for which gear you're in. I've just changed out the Neutral Safety Back-Up Switch on the side of the transmission thinking that was the culprit, but no change. I've gone over every fuse and relay. Something else odd is that there's a loud relay-like clicking sound coming from my steering column now when I press the brake, which wasn't even noticeable prior. I called a cluster repair service to see if that maybe the problem and they said my cluster is fine, that it's my shift indicator sensor. I have no idea what that means, as I can't find any part on my truck named that, unless he was referring to the NSBU sensor. Any help would GREATLY be appreciated. I'm losing my mind over this.
