I got 97 and same setup as yours. The AC light should light up when you turn the side marker/dash lights on. Probably the bulb is bad. It is pain to access the light. Try this, remove the front black cover and then there should be a transparent plastic piece that carries the light to the panel. Try removing the plastic panel to access the bulb. The bulb is the same bulb goes into the front marker light bulb / large dash light bulb.
