I would guess the Center High Mounted Stop Lamp (CHMSL) was not working
before the sunroof was installed. If this seems probable or at least
possible to you, remove the bulb and test it with a continuity tester. If
the bulb tests "good" then test for 12 vdc at the bulb socket while the
brake pedal is depressed. There are several wires from the brake switch to a
couple of electronic devices including the brake lights. I would think the
CHMSL wires would be included in the bundle going toward the brake lights
rather than be routed singularly through the headliner area.
