I have a 93 Toyota pickup - the blinkers and reverse lights work but the brake lights don't work. I changed the bulbs and also replaced the entire light assembly. I checked the fuse and replaced it- still no brake lights. The brake running lights don't work either- any suggestions???

So your taillights should have 2 bulbs in them. 1 that turns on when you turn your lights on and stays on until you turn them off. That same bulb should have a 2nd circuit that lights up when you press on your brakes. The 2nd bulb appears when your reverse gear is engaged. So if you have no lights on right you have to replace both bulbs and if you have no brake light on the left you just have to replace your rear brake light bulb.

Manual or automatic transmission.

That should be on two different fuses, but everything goes thru the turn signal switch.
The switch might be faulty. A mechanic would check for voltage there.

could be reverse light globe, reverse ligh switch on gearbox, or wiring.......being an older vehilce, the revers light wiring is fairly simple

I have the same problem -

All lights are good - Fuses Good - Brake lights don't go on

Did you fix this problem ? How ?

If the blinker and reverse lights work on the bad side maybe a new socket.

check all bulbs,inspect sockets for corrosion,rust ,or sighns of overload.follow wires and check connectors if all good ,replace the flasher ,,if that doesnt fix it ,the blinker switch in the steering coulmn would be next

I have notice that this is a common problem. The socket most of the time goes bad, I don't know why but they just do. You can pick them up at any parts store for around 5.00 each. If you don't have a volt meter and ground straps to test it right, then I would try changing the sockets out. Quick and easy. Let us know how it goes.

bad ground and or socett bad

Assuming you don't have a trailer connector the bulb failure warning module might be you problem
