Rear Right Brake Light Not Working.

[Anthony DeVor]

According to the following link, there is a flasher: "Flasher unit is next to the blower motor relay under the dash."

(I have no idea if there is a flasher in a 1998 Expedition ..... just trying to help.)

Anything really before 2005 SHOULD have a flasher relay and is usually under the dash on the driver side by the steering column usually
