Question about 1993 Jeep Cherokee Country

Turn signals don't work

Left and right front and back turn signals stopped working. Fuses are good and hazards work all the way around. Narrowed it down to a switch I think. Bought the switch and can't figure out how to replace it.

    A) If the flashers work, could that still mean the turn signal relay is out?
    B) Wouldn't the lights still come on, but not flash if it was the relay?

For 3 bucks or so, I'd do what bunnydawg suggests & look for the signal flasher & replace it, or try 4 way flasher in signal flasher spot & it will tell you.

Turn signals not working


all else on car works perfectly (other shoe drops??????)
waring 1: no scan tool, you will fail (99%)
is battery fully charged to 12.6vdc rested or at 10v?
all 4 corners dead?
not working means dead?, flashes too fast/slow or dim? or they stick on? (5 modes to fail not counting L/R and haz)
do the hazards work? (prime evidence and not stated)
most cars before 2007 have fuse marked TURN.
but not this car... its not at all like older cars....
did you scan it first after the fuse tests? any PCM scan tool.?

the FSM chapter 8L shows the huge list of errors the lamps can fail. DTC errors.
in fact 8 blinker codes, ! DTC errors,

there is no fuse, just for turns, (trailer lamps fuse 19)

read this excerpt from the FSM book.

The turn signal system operates on battery current received on a fused ignition switch output (run) circuit so that the
turn signals will only operate with the ignition switch in the On position. The hazard warning system operates on
non-switched battery current received on a fused B(+) circuit so that the hazard warning remains operational regardless
of the ignition switch position. When the turn signal system is activated, the circuitry of the left multi-function
switch and the FCM will cause the selected (right or left) turn signal indicator, front park/turn signal lamp, front side
marker lamp and rear tail/stop/turn signal lamp to flash on and off. When the hazard warning system is activated,
the circuitry of the hazard warning switch and the FCM will cause both the right side and the left side turn signal
indicators, front park/turn signal lamps, front side marker lamps and rear tail/stop/turn signal lamps to flash on and
off. The Front Control Module (FCM) can also activate the hazard warning system lamps.
end quote)

the module front control MFC, runs this
and it uses fuse 18 , if 18 blows the module goes off line and vast things fail and huge numbers OF DTCs store.
and fuse 27 MFC
MFC needs these fuses good.
keep in mind nobody has MFC internal schematics...so........



this module drives left and right side front and rear.
electronic drivers, not fuses.
the MFC is here.
the fuses are 12,13,18, 20,27 that power MFC.

My right front turn signal not working the bulbs are good and so is the fuse but I don't have fire going to them it's a 2010 chevy 2500hd


You don't have fire , never heard it called that before ! Battery voltage , power but never fire ! An open CTSY fuse located in the I/P fuse block will affect the operation of the right front turn signal only
Turn Signal/Hazard Lamps When the turn signal switch is placed in either the left or right position, a ground signal is completed from the turn signal switch to the BCM. When the hazard flasher switch is activated, a ground signal is completed from the turn signal/hazard switch to the BCM. The BCM then sends an ON-OFF voltage signal through the fuses to the appropriate turn signal and side repeater (export only) lamps or to all of the turn signal fuses for hazard operation. The driver door switch and passenger door switch also receive voltage from the BCM turn signal supply voltage circuits for the mirror turn signals. The door switches have no function or control of the mirror turn signals other than a pass through connection for the circuits. The audio chime is also activated when the turn signals are ON. The instrument panel cluster (IPC) receives the signals to activate the turn signal indicators over the GMLAN serial data system. When the hazard switch is pressed, all turn signal lamps will flash including both IPC turn indicators.
Ground is applied at all times at G201 to the turn signal/multifunction switch. The turn signal lamps may only be activated with the ignition switch in the ON or START position. When the turn signal/multifunction switch is placed in either the TURN RIGHT or TURN LEFT position, ground is applied to the body control module (BCM) through either the right turn or left turn signal switch signal circuit. The BCM then applies a pulsating voltage to the front and rear turn signal lamps through their respective control circuits.

Front right and back right turn signal wont work but the front left and back left do


first check the bulbs on that side by visual or changing to the other side if you can't see that well if the bulbs from the front and back work or are good when checked the flasher has blown out on one side and you have to replace it other possible cause could be a broken wire for the right side lights so look at the connectors for that side front & back if all is good one more thing could do this the actual turn signal lever that you use to activate the signals could be bad for the right side especially if it does not go back to the normal position after making a turn and the steering wheel rotates back to it's normal position but the turn signal lever does not click back to the center position this would burn out that side from the signal constantly being on good luck stephen

On my 2004 impala, the front right turn signal doesn't work, (only works with hazard lights). And the back right signal is fast. The signal "clicking" sound is non stop but on the other hand...


If the turn signal filament of the right front park/turn lamp is known to be OK and the hazard switch is in the normal position, the hazard switch or the turn signal/multi-function switch could be defective

The headlights work but turn signals don't and hazards don't work either and brakelights still don't come on.


one bad bulb will be your problem. Doesn't matter which side. If one bulb is bad in the front or in the back, left or right, then you have the problem you are having. Check your fuses first. Little easier to change a fuse than a bulb.

96 Ford Taurus no turn signals or hazards


Take the turn signal lever and jiggle it, a lot. If they start working, the switch is bad. You can also turn on the hazards and take hold of the button and push it left , right , forward and back and see if they start working. If so, replace the turn signal/ hazard switch.

1993 Dodge Shadow...left turn signal won't flash


If the fuses are good and the front and rear bulbs are good, change the flasher for the turn signals, even tho the right is working. If that doesn't fix the problem, it might be in the turn sgnal switch on the steering column.
If both bulbs are good for the backup lights and fuses are good, then the backup light switch, which is screwed into the side of the transmission has to bad.
