Why are my Rear Brake lights not working
We checked the fuses and they seem fine. Two years ago we had a huge problem with the wiring harness, it would loosen it's connection from our dirt road and the truck would just shut off.

nancy , Do you have rear signal lights? If bulbs, bulb sockets, fuses and brake light switch all appear to be good the fault is probably the turn signal switch. Also there is a trailer light harness on the vehicle check at that connection or actually remove the trailer light harness as some have a built in converter that can cause weird issues also. Links below may have some useful info. for you as well. Good luck.
I hope this helped you out, if so let me know by pressing the helpful button.

Assuming you have already replaced the bulbs, there is a switch that the brake pedal touches when depressed that activates the lights. I've seen this switch knocked out of place before or even broken.
Here are two links. The first, the guy shows the location and basic overview of the brake switch in a 2004 Expedition. The second, shows an actual replacement for an 2004-2008 F-150.

Check the wiring at the multifunction switch in the steering column. The molded plastic connector is vulnerable to cracking & allowing the individual wires to become disconnected. Fixed mine...

The multi-function switch was the problem disassemble the multifunction switch inside all the contacts were corroded green and non-working cleaning the multifunction switch isn't hard and it saves you about a hundred and sixty bucks for a new one

Mark, I had 3 different 89 econolines, all with that issue. its a weak ground. what you need to do is find which wire is the ground wire coming from the light, and splice an additional wire onto it, and attach the other end of the new wire to the body or frame.
