Okay so my ranger has hazard(turn signal flash) and running lights but not change in brightness of light when I press brake pedal. I just unplugged the sensor from pedal and took plug off of it. Used a wire and jumped power across and the brake lights did not come on. I then check again and flashers and running lights are still working?

 

In 1989 the turn bulbs are not shared with brake lights, that was 2000 and up Rangers

The park lights and brake lights use a Dual filament bulb, so share a Ground wire, but use different filaments

There is a separate brake light fuse in the cab fuse box, probably 15amp, try fuse #4 thats what it was in 1990 Ranger
Now the 4 way flasher shares this fuse, but NOT turn signal flasher
So try 4-ways, if they are not working then is most likely the Fuse

1994 and earlier Rangers have TWO flashers, turn signal and separate 4-way flasher, 1995 and up just have ONE flasher thats shared

 

the left and right turn signal work aswell as the 4 way flashers. But the brake lights the self do not light up when pedal is pressed.

 

If 4-ways work then fuse is OK

Is there a 3rd brake light on the cab?
And does it work?

There is just 1 brake light wire that runs inside drivers side frame rail to the rear of the truck, and on drivers side rear it Splits to run to the 2 bulbs
People often add Trailer light wires at that location, drivers side rear, and over time these added Splices can corrode and cause wire failure

Brake light wire will be a Light Green wire

 

So something has happened overnight. The turn signals, flashers, nothing works anymore?

 

Mice?

Start at the battery, needs to be 12.3volts to 12.8volts or its a bad battery, or needs to be recharged, so bad alternator

 

When I turn on my headlights/running lights they turn on. But no 4 way flashers, left or right turn signal, no third brake light or brake lights. I hope I am helping and not being annoying. I just really need this thing to be able to get me back and forth to work without a ticket every day and night

 

Head lights and running lights are separate systems with no connection to flashers or brake lights, but it would mean battery is not dead

And you have re-checked the fuses?

You really need a 12volt test light or volt meter to go much further, there are alot of wires and parts in a vehicle to just guess as you go

 

I have used a test light on all fuses and every fuse in under dash fuse box is getting power to both sides of them. Every fuse underneath the hood is also getting power to both sides. Something I forgot to mention is before when my turn signals were working it would do the “click” bit now it doesn’t. I checked power to the signal flasher in fuse box and it gets power to “left probe” but not the top. I would assume as it sends signal through the flasher to do that.

 

The turn signal flasher, on the front of fuse box, has 2 prongs, one gets 12v with key on, the other prong is connected to the Turn signal switch/stalk

When you move the stalk in one direction it connects the Flasher to the 3 turn signal bulbs on that side, front, rear and dash board, those 3 bulbs light up and draw a few amps, this causes the flasher to over heat and disconnect, turning off the 3 bulbs, flasher cools off and reconnects the 3 bulbs light up again, flasher heats up again................ect

If one of the 3 bulbs burns out, then the other 2 will come on but won't flash, because flashers is not getting hot enough to disconnect, not enough amps are being used with just 2 bulbs
If you switch to LED bulbs the same thing can happen, bulbs on but no flashing

If you hook up trailer lights then there would be 4 bulbs on one side, and you will see the flasher heat up/disconnect faster, so faster flashing


None of that is helpful I an sure


But not sure what to tell you, turn, 4-way and brake lights really don't have any common wiring that would cause all 3 to quit working
The brake only have the 3 bulbs and they all use light green wire
Turn signals use separate wires and 1 to the front and 1 to the rear, so if both front and back are not coming on then only common point is the turn signal switch/stalk, but its has no connection to brake lights in 1989

 

89 Rangers are just a 1 bulb system, brake/turn use the same element, plus backup light

I think it's just the 93 to 99 that have the amber turn signal.

Also I don't think the 89's have a center mount brake light, almost positive it's just a cargo light.

My guess is your turn signal switch itself is bad.

 

i went to oreilleys and the switch is $150 but is special order. I checked power to the brake switch on the pedal. I have no power at either side of the plug. So power isn’t reaching the switch somewhere. Also my turn signal switch has only ever worked on 2 settings so this could very well be it and it finally bit the dust. I hope this fixes it! Someone had put some lights shining in the floor that would come in with the headlights/running lights. I removed all the wiring as it was all pretty badly done and I didn’t need it. And now my battery voltage gauge isn’t working anymore. I am assuming there was a ground somewhere for that gauge I must’ve undone? Can anyone point me in the direction to get all my dash lights working again(wiring diagram) and how to get cluster out. I tried pulling it out and I could only move it forward about 3 inches. The Speedo(thick black) cable is too short to let it come out any further. And only my rpm gauge lights up at night
