1998 Ford Explorer No Brake Lights

Electrical problem
1998 Ford Explorer V8 All Wheel Drive Automatic 115000 miles

Having a problem with the brake lights on my Explorer. I have no regular brake lights when the pedal is pressed, but the third brake light (LED) works fine. The weird part is that even when the brake pedal is not pressed the third brake light continually flashes at a very high rate, almost like a strobe. As a sided note I also noticed that the door locks stopped auto locking when you put the vehicle in gear at about, or the exact same time the brake light problem started.

What I have tried so far:

1 Checked bulbs and fuses
2. Checked brake light switch (LED third brake light still flash even when brake switch is disconnected)
3. Checked turn signal switch (LED third brake light still flashes when disconnected completely)
4. Checked wiring in steering column and under dash and could find no visible shorts or damage to wiring.

Any ideas? I don't know what to look at next.

Thanks!

Most common is the combination switch on the steering column

put 4way hazards on off on and then check if they work

Thanks, but no good. No matter what I do with the emergencies. As mentioned, the third brake light continues to flash even when I completely disconnect all the wiring from the turn signal switch.

Thanks again for your help.

Has anyone come up with a solution to this problem. I have a 98 Ford Explorer with the same problem. I've checked all the wiring, it's ok. The only thing I haven't done is check out the multifunction switch. I do have a book that shows how to do that so that will be my next step. Any input or info would be greatly appreciated. Thanks SkipperDan

I checked out the multifunction switch and it is ok. I did find on my stop light switch that has five wires in the plug that two of wires on the plug are hot. I don't believe that this is incorrect. Any input would be greatly appreciated. Thanks

Have a helper watch the lights for you as you go under the steering by the brake, twist and move the brake light switch looking for a short
also hold the switch
trying to make the flickering stop
and if it does try to get it going again finding the reason
hope I m not confusing you

also does the 4 way flasher work?
Push the 4 way and step on the brakes does that make any difference

also one more question
how did you determine that the multifunction switch is good?

Praise God I found the problem! :-) I removed the top mounted brake light and found a faulty connection which stopped the strobe light effect. Note: The top mounted brake light still was on very dim but not strobing. Then I rechecked the left stop light socket and found that the female prongs were not really that clean so I cleaned them up and also did the right side. I also installed new bulbs, fiqured I might as well as I was in there. And all is great and back to normal. I have brake lights. So, if any one else is having this problem I strongly suggest to start with the fuses and then go directly to the brake bulbs and sockets before thinking it is in the multifunction switch! And running all those test. Thanks for all the input and suggestions! SkipperDan is ready to take on another task! :-)
