It no longer works and the digits/buttons do not illuminate. Nothing out of the vents either. The radio and everything else work fine. It's like someone unplugged the head unit

Try disconnecting the negative terminal on the battery. Then reconnect it and turn the ignition to run, or start the engine. If there's power to the climate control unit it will default to auto and you'll get air blowing out the vents. Also, the radiator fan will turn on. If it doesn't, you'll need to pull the unit and verify power and ground at the connector. Opening the unit to get to the circuit board inside will be pointless if it isn't getting power. Have you tried tapping the face of the unit? If the circuit board pins are loose the lights may blink from tapping on the face. I pretty much did the same as VikingTrader. Bent the terminals up to make contact with the pins on the circuit board. Clean them first. Has been working perfectly since. Try the other things first. Don't tear the unit apart if you don't have to.

(BTW: that's how I first noticed. Not having to turn it off when I reconnected the battery)

The circuit board is inside the unit. You'll have to separate the face from the body. This will require breaking it. DON'T PANIC, you only have to break the plastic nibs that hold the face on. There are also two clips on the side. Before you break it open, make sure there is power at the connector. Not sure which terminal supplies power. Probably a red wire with black being ground. Do you have a FSM? If not I imagine you can Google a wire diagram for it. Probably one right here on the forum somewhere.

ABS and Climate control work now but I ran into a starter/vats issue. I started a new thread for that one: https://www.corvetteforum.com/forums...post1589877872

Right, sorry. One step forward and 2 back...
It turns out the wiring was messed up causing the GUAGES fuse to blow. Since I was dealing with 2 cut pink wires that looked identical I wired them the opposite way I did initially and the GUAGES fuse did not blow.
