1. Headlight switch: The headlight switch is responsible for controlling the power to the dash lights. Make sure that the headlight switch is turned on.
2. Dimmer switch: The dimmer switch controls the brightness of the dash lights. Make sure that the dimmer switch is turned up all the way.
3. Wiring: There may be a problem with the wiring that supplies power to the dash lights. Check the wiring for any loose or damaged connections.
4. Dash light bulbs: The dash light bulbs may have burned out. Check the bulbs and replace any that are burned out.
If you are still having trouble getting your dash lights to work, you may need to take your Aerostar to a mechanic for further diagnosis and repair.
