Have a 89 dodge raider;;have no turn//4-way flashers or brake lights;;all fuses good;have power to brake light switch and leaves switch when apply brakes;;found round flasher[4 way flasher]know this because have power to it on one side and when pull 4-way fuse loose power;;square flasher beside it;has power to it;loose power when i pull turn fuse[also when i remove turn fuse i loose warning lights on dash and hear relay on middle or pass side kick out]i got another turn signal switch[columum switch]from wrecking lard[said they check before removing]plug it in same thing;;it doesn't have headlight washer but don't think that would have anything to do with turn/4-ways/brake lights''also no overdrive;;;

FUSES BAD OR MODULES AND SWITCHES
NO BCM brain box here.
USA car , canada is NO THE SAME electrics !!!!
so flashers means turns, and turns are dead all 4 corners or what? all flasters is HAZARD lamps switch
parks work.(tails and front parks)
turns fail all 4 corners(not told) and hazards dead too all four corners and brake lamps all 3 rear dead.
do not break the brake lamps.
grounds to all lamps good,(the failed ones)
0vdc on ground.
fuses are always first, a 20cent fix. is way and childs play test (or a look)
fuse 1 and 9 not blown in IP BOX x2 , 15amps
OMG fuse 9 runs brake lamps. is this clue , YES
the next in LINE is Electronic flaster not bad.
5 wires and the black ground wire not busted.G204
next in line is the very complex MULTIswitch (column)
next is the BRAKE PEDAL switch NOT BAD.
if not bad 12vdc (push brake pedal) leaves the switch
R/GL wire to all brake lamps including 3 center high mounted lamp and its G300 ground

fix brake lamps only first.
fix that and others get fixed for free (shirt tails free)
to test lamps at rear for brakes the pedal must be depressed . a 2 man job.
fuse 9, hot both sides. and is hot all the time bat side.
brake switch LG/R wire hot all the time key off too.
light green red !
step on brake R/LG goes hot, now. if not switch is bad
Red/light green. (means)

The high mount brake light gets its own signal from the brake light switch (on the brake pedal). Or at least the wire leaving the brake light switch will splice, one wire to the high mount brake light, and the other for the rear brake lights is routed through the turn signal switch, and coordinated there with the turn signal wires to the rear brake lights. The brake wires and turn signal wires share the same wire, and same filament in the bulbs. It is kind of complicated, but brakes applied with no turn signal, brake light wire goes from brake light switch through the turn switch and out to the bulbs. If brakes applied with turning signal, non blinking brake light wire goes from turn switch to rear light, while the turning signal wire will go through the flasher relay, and then to the rear light to cause blinking.

I hope that makes sense. It appears the problem may be in the turn signal switch for both the turn signals and the rear brake lights.

Hazard switch might be on

Three places to look. 1) Brake lamp fuse, 2) Turn signal switch and 3) the brake pedal switch. Brake light power comes from the fuse up to the turn signal switch down to the brake lite switch on the brake pedal and then on to the light bulbs. Start by putting the 4 way flasher on. If the brake lites flash, then the bulbs are good. That eliminated the fuse too. so the problem is the other two.

It could be the turn signal switch, since the brake wire travels through the turn switch after it leaves the brake switch and then goes to the bulbs. That is how you get a steady brake light on one side, and a blinking light on the turning side. The rear turn signal lights and brake lights share the same filament in the bulbs (and the same wire). The wire on the turning side has to first travel through the flasher relay.
If you have a test light, first check for power out of the brake light switch with the pedal depressed. Then check for power in and power out at the turn switch connector-power in on the brake light wire and power out on either of the wires going to the rear bulbs-if no power out, the turn switch is bad-brake pedal still depressed so you still have the signal.

work on one thing at a time, brake lights first, check the brake switch, is it mounted ok ? is power geting to it ? replace if any doubt. check all fuses, replace 4-way flasher, cheap fix . a repair manual has good info, including wire diagrams, for all circuits, etc.,,.. check wir harness @ rear of truck, & along frame for damage, corrosion, etc.,.

Have yoiu changed/checled the lightbulbs? (In other words,do your turn signal lights work? If the front turn signal lights work, but the rear don't, then turn on your four (4) way flashers. If the rear lights still don't work, then all the bulbs are bad. It is rare for all the bulbs to be burnt out at the same time, but it does happen.

If the turn signal/four way flasher lights work, then you probably have a bad brake light switch. However, first check your owner's manual to make certain there is not a separate fuse for these lights. If there is, then swap the fuse for the brake lights for another fuse (or relay) of the same size/amperage. (Facing the hood, the power relay box is located on the right side (usually) under the hood.)

The fuse box is located under the dash, on the driver's side of the car. Usually there is a plastic cover that has to be removed to access the underside of the dash, and then there is a plastic cover that has to be removed to access the fuse box. If you don't have an owner's manual, nprmally the fuses and power relays are normally marked on the plastic covers your remove ot access the fuses and power relays.

If the fuses/relays are good, then you have a bad brake light switch. This is located on a bracket just above the brake pedal. When you push the pedal down, the switch makes contact. Disconnect the plug to the switch, and jump across the plug contacts (not the switch) with a small piece of wire, or if a piece of insulated wire is unavailable, you can use a paperclip, you won't get schocked, just make certain that the paperclip does not come in contact with a ground while you have it plugged in to the plug for the brake light switch.

If the lights stil dont work, check for power to the plug for the brake light switch. If you have power to the plug, the turn signals and four-way flashers work, then my guess would be that you have a broken power wire (probably iside the steering column, or a bad turn signal switch. If the brake lights work whe nyou jump out the brake light switch, then the brake light switch is defective.

Do you have power at both sides of the brake switch when the brake is applied? If so it sounds like the turn signal switch is bad. try turning on and off the 4 ways a few times. sometimes this will clean the connections and it will start working.
The power goes through the fuse to the brake switch. from the brake switch to the turn signal switch from the turn signal switch to the tail lights. If the 4 ways are on the power goes through the 4 way fuse to the 4 way flashers then to both sides.
If the turn signal is on and the brake is on, the turn switch cansles the power from the brake and uses power from a 3 fuse and flasher for the side that the turn signal is called for.
If I typed to fast let me know. I can answer any questions you might have.
If this helped you please vote 4 thumbs up. :-)
good Luck and God Bless

A bad flasher would not usually cause no brake light, the problem you are discribing sounds like it could be a bad multi function switch, that is the turn signal/hazard switch, everything you have that is not wrking, goes through that switch on most cars. Would need to look and a schematic to make sure and do some voltage checks, but that is the direction I would trouble shoot it in.
