The only thing that will work with key OFF is the brake lights,head lights and emergency flashers. Dome light will also work.
It's the turn signal switch which is the culprit.
The turn signal switch in the colum could be bad COULD B the TurnSignal switch OR the Flasher 4 the Emergency FLASHERS (because there is 2(two) Flashers & the Brake light Switch on the Brake pedal could B Bad.(turnsignals Have there OWN Flasher) the emergency flasher switch has 3 electrical contacts.sometimes they overheat and melt into the red flasher switch deforming the whole switch.unfortunatly the whole blinker and flasher needs to be replaced.
TRY TURNING THE EMERGENCY FLASHERS ON AND OFF A COUPLE TIMES THEN CHECK YOUR BRAKE LIGHTS. WORKED FOR ME.
It depends on the car. Some cars require that you turn on the turn signals to make the 4-way flasher work. If that's the case with your vehicle, make sure the emergency flashers aren't on. Otherwise, it's probably a problem with the turn signal switch.
Start by checkin all fuses and then go through all your wirein to rear lights and the check build recepticals for wear and corosion..
On the 1979 B200 Sportsman V8 if the brake pedal makes all signal lights come on and hazards and flashers do not work on their own, it could be the flasher, but the culprit could also be a burned out bulb or a short in the wiring.
You may want to check the brake lights.Everything runs through the multi-function switch.(the turn signal switch)
First thing I'd check would be the fuse for the stop lights. If it is okay the next thing I'd check would be the stoplight switch located under the dash where the brake pedal is suspended.
You probably need a new turn signal switch. I have a '96 Monte Carlo and I had to replace the turn signal switch to get the brake lights to work. Thankfully I had a brother who knew how to take off the steering column and replace. Hopes this helps!!!
I am having the same trouble. My brake lights work with the light switch for nighttime driving, but only far right brake light works when i pres brake pedal. Reverse lights dont work at all. Turn signals and hazard light work.

Probably the turn signal flasher
Possibly blown fuse, bad brake light switch, or blown brake light bulbs.
Because the brake lights are the priority circuit.
the turn signal switch is probably bad
The wires go thru the turn signal switch which may have a bad ground. Try and pull back on the turn signals and see if the lights come on with your foot on the brake....
If you have the same bulb for brake and signal, brake light power needs to be interrupted by the signal lights, The brake circuit has to go through the signal light switch so the problem could be there.
First check the fuse. See if it's blown and if not check it for 12V with a test light. If you have 12V at the fuse go to the bulbs and be sure they are not blown. If not go to the brake light switch. You should have 12V going into the switch. Depress the brake pedal and check for 12V coming out of the switch. If all this checks out okay the problem would probably be in the signal switch. Do the emergency flashers work?
The flashers are in the DS fuse panel, behind that fuse panel there is also a flasher relay that controls the truck and trailer signal lights and the trailer brake lights. To get to the back of the fuse panel you must take the bottom part of the dash off.
Mounted on auxiliary fuse block under the driver side dashboard, above the left side of the brake pedal. There are two flashers at the top of the fuse block. The one on the right is for the turn signals, and the one on the left is for the emergency flashers. Just pull towards the rear of the car to remove either. You can test for function by swapping one flasher for the other, or temporarily regain turn signal use by swapping in the working emergency flasher.
Please check the Brake light switch....The brake light switch should be located near or on the brake pedal (up on the stem of the brake pedal)
ignition will be turned off and keys left in ignition, transmission placed in park (automatic) or reverse (manual), parking brake set, parking lights/emergency flashers on
in dash lights
