Question type: Maintenance & Repair

Brake lights don't work, not even the one over the rear window. Front blinkers work but flash very rapidly. Right one started doing that a month ago now both are doing it. Lower bulbs look fine, didn't chk the upper one. Swapped out fuse. Still no good, brake lights are dead. Tail lights, back-up lights and parking lights all work as do the hedlamps. Just replaced brake light switch under the dash; still no good. Any suggestions?

The rapid flashing suppose to notify the operator of a faulty bulb. The clicking noise inside the cab should also speed up, that portion of the system is working as it should. If you use a meter on each socket in the rear which is not working you will find current is not reaching the bulb. You'll probably need a Hayne book, or other variety, that shows the wiring diagram for the tail lights. Personally, I'd check the wiring backward for current. Begin at the rear and work yourself toward the front.

YOur description of the problem is a little confusing. It appears the rear brake lights do not work, but everything else does? Is this correct? I checked the wiring diagram for a 2003 Explorer, there are four possible different configurations, but are similar. Determine which side (left or right light) is the termination point of the circuit and begin checking the opposite one. While someone is standing on the brake, use a meter to see if current is reaching the socket. If it is not, then the problem is backward. If it is reaching the socket you probably have a bad socket which needs replacement. The diagram I have shows current being fed from one socket to the other. My diagram shows no relays (fancy name for electromagnetic switch) between the pedal and the lights. Also check the current at the light switch at the pedal. If something is not working other than the brake lights, please advise
