Go under the truck at the back of the box. Between your 2 frame rails, on the driver's side look up and you will see a plug-in. This plug-in runs all the lights on the back of your box. Use a test light and check both sides of it for power. My guess is that you will have power on the cab side for brakes but none on the tailgate side. To repair just splice across the connector. Use heat shrink tube instead of black tape to cover the connections. It works much better at keeping water out.
If there is power on both sides of the plug-in then check the grounds from the light sockets to make sure they are good. You may also need to change the sockets. they sometimes wear so the bulbs don't make contact.
Hope this helps.

    Thanks for your help. It was actually the plug that runs from the steering wheel to the fuse box. It had melted the brake light wire where it plugs into the long flat white plug that goes to your blinker switch.

Do the brake lights share the same bulb as the turn signals? If so the brake light circuit goes through the turn signal switch inside the steering column. There could be an open in one of the wires or a contact in the switch causing the brake lights to not work.

How to fix no brake light issue on 1999 Expedition


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.

Where is the brake relay on a 2001 gmc sierra.


Try wiggling the hazard light switch while pressing on the brakes.The taillights are connected to the turn signal switch before it goes to the brake switch.The contacts on the hazard switch are probably dirty(I remember this problem years ago,same symptoms-3rd light works but l/R tailights not working).You may just be able to turn the hazards on+off a bunch of times to clean the contacts instead of replacing the switch.

I bought a 1995 truck and the brake lights aren't working I noticed ythat the hazzard light switch is busted up could that be the source of my problem


Check the fuses. And check for power at the taillights (These taillights have circuit boards on the back side that can go bad.) I don't think the hazard switch is it because the brakes would still work. Also check the brake pedal switch. There is a hazard flasher, does the hazards work?

I have a 1992 Buick La Sabre Custom. My brake lights are not working but taillights, turn signals and hazard lights do work. Switch ok. fuse ok. ????????


if your fuse is good. and you have power at the brake light switch and when you hit the brakes you have power coming out the otherside of brake light switch/which would be the white wire/ check that the white wire is sending power up the turn signal switch. if theres power there and your turnsignals work? im afraid that your turnsignal switch is bad rare but it has been known to happen.

Having problems with brake lights. The hazard light and blinkers are working when applied. When I apply brake the centre light on hatch door works but the two side lights don't work


Well the fact the high mount/3rd brake light works proves brake light switch is working. I would suspect factory trailer connector wire which feeds off tailight is broken. Follow wire from plug back to left taillight where it is exposed to the elements.
