I have no brake lights on my 1999 Ford Expedition. I have replaced the bulbs and changed the brake switch. I can't see any wires at the harness broken, or under the dash behind the brake switch. Is there any thing else I can check?
Have you tried wiggling the hazard light switch? The brake light switch puts 12 volts to the hazard/turn signal switch,and the switch will apply this to both taillights.If you turn on the left or right turn signal,it will only route 12 volts to the other light.If you turn on the hazard lights,it will only allow the 3rd brake to come on due to the brake switch.Often.the hazard light/brake light contacts get corroded due to not being turned on and off regularly.Have someone watch the taillights(or use a mirror) to see if they come on when you wiggle the hazard switch.If it does,turn the hazard light switch on and of repeatedly to clean the contacts.
SOURCE: brake light issue.
the brake lights switch of the expedition is connected to the cruise control system. get yourself a wiring diagram and sort out the problem. i have read of fires being caused by that problem so be carefull.
