Multi-function switch is bad (assuming the correct bulbs used).

The brake pedal switch has to be good or the 3rd brake light would not work. The fuses have to be good for the same reason.

2003 GT Convertible (sold & missed)
2000 GT coupe (Craigslist project. Fixed. Now my DD). Windsor to Romeo swap.
