Also, if there's a fuse plugged in to the back of the radio, that is an aftermarket replacement radio, not an original. If it has a digital display, it must have two 12-volt feeds, one switched from the ignition switch to turn the radio on, and that other constant 12 volts to maintain the station presets and clock memory. The harness for this radio is spliced to the car's original radio harness. The two wires in question are a red wire for the switched 2 volts, and the pink wire for the constant memory 12 volts.
It's the pink wire we're concerned with. Rather than tearing a splice apart, that wire feeds the red 10-amp fuse on the back of the radio. Those fuses have two very small test points on top. You must have 12 volts on both of them. If it's missing on both, that will explain why the radio is dead. Don't worry about the radio in that case. It will work again once the glove box light issue is solved.
A test light works best for this type of problem. You can use a digital voltmeter too, but under the right conditions, they can give false readings if the plug is disconnected from the radio when the readings.are taken at that plug.
