My brake lights on the back of the van do not work. Well, one works, the one in the back but on top (the long one). I had a friend put all new fuses in. Put all new bulbs. He checked for bare wires, corrosion, anything that didnt look good. Everything was fine, all intact, no nothing back there. Wondering what the problem might be. The shop wont give me a price cause they need to take it in and look around. Just wondering if it was something I could do and not spend all my money at the shop.
I have had the same problem on our van. The plastic housing that the bulbs snap into for some reason overheat and melt a bit. Then the connection wires on the new bulbs do not make contact to the socket. So, if your bulbs are good and still not coming on then this is likely the problem. You should be able to see melting around the contact wire in the housing. I just use a tooth pick or something small to jamb in behing it so the wire will make contact again.

Buy a cheap multimeter and measure your voltage at the bulb when the brake lights are supposed to be on. You should have 12vdc. Is your 3rd brake light and brake lights on the same fuse? If not, measure to see if you have 12vdc at the fuse itself.
Double filiments in the brake light bulbs allow brake lights and turn signals to work, it"s possible both your brake light bulbs are burned out even though your turn signal lights still work. The top brake light still works which means electricity is reaching the brake lights.
well u have two seprate problems the hazards and turn signals have a flasher that needs replacing if the fuse is good on the fuse box marked signals .and there is a brake light switch under the dash board near the brake pedal it has two wires on it check the wires make sure they are connected if so replace the brake light switch
check the fuse for the brake lights. The brake lights and siganl lights use the same bulb filament. The parking and running lights use a dimmer filament in the bulb. There are 2 filaments.
Your brake lights work through the multifunction switch which operates the signal lights. If the signal lights work, you may have a bad brake lamp switch which is on your brake pedal arm.
Let us know what you find.
the problem is probably your turn signal switch. I know it sounds weird, but the brake lights work through the switch. If the third brake light works, then the brake light switch works, the turn signal switch works the lower brake lights. It's the switch under the steering wheel inside the column...not the easiest or cheapest thing to replace, but should fix your problem. If you decide to do it yourself, tie some wire to the connecter on the end of the switch wires at the bottom of the column...that way when you pull the wires up throught the column, you can use the wire you tied to them to pull the new connector and wires back down through the column.
