I would be checking the wiring for a short circuit, possibly around the steering column, or check around the indicator lights for possible cuts in the loom or water ingression that might be causing a short. basically check all from switch to lights.

SOURCE: location of flasher for turn signal

  1. Access the COMBINATION Turn Signal and Hazard INDICATOR FLASHER on the Left-Hand (drivers) side of the instrument panel in the fuse junction panel.
  1. Remove turn signal flasher/hazard indicator flasher by pulling indicator flasher straight out.
  1. To install, align the terminals of the flasher and press into place.

Try replacing the electronic flasher. It will be located below the left side of the dash in a relay box. Should be blue in color

The hazard back lights wont quit blinking when car is running even when i pull the fuse on a 2002 buick regal


What fuse are you pulling ?

Hazard Lamps
The hazard warning switch is part of the turn signal switch. The turn signal switch receives battery voltage at all times through the HAZARD SWITCH Fuse. When the hazard switch is placed in the HAZARD position, battery voltage is applied to the hazard lamp/turn signal lamp flasher. The hazard lamp/turn signal lamp flasher sends a turn signal flasher signal to the turn signal switch. The turn signal switch provides all of the turn lamps and turn indicators with the turn signal flasher signal, simultaneously flashing them on and off.

Turn Signal Lamps
The front turn signal lamps are made up of the front park/turn signal lamps and rear turn signal lamps. The front turn signal lamps flash with the rear turn signal lamps when a turn is initiated using the turn signal/multifunction lever. The turn signals will operate only with the ignition switch in the RUN position and will not operate during hazard flasher operation.
When the ignition is turned to the RUN position, battery voltage is supplied to the TURN SIGNAL Fuse. Battery voltage is then applied through the turn signal fuse circuit to the turn signal switch. When the turn signal switch is placed in the LH or RH position, voltage is supplied to the hazard lamp/turn signal lamp flasher. The hazard lamp/turn signal lamp flasher supplies a turn signal flasher signal to the turn signal switch. With the turn signal switch in the LH or RH position the corresponding turn signal indicator, rear turn signal, and front turn signal receive the turn signal switch signal and will flash. The front turn signals receive the turn signal switch signal from the turn signal switch via the BCM. The turn lamps are permanently grounded.

Replace the turn signal switch. Refer to Multifunction, Turn Signal, and Hazard Switch Replacement - On Vehicle in Steering Wheel and Column - Tilt.

My turn signals don't always work and the flasher warning doesn't seem to work. I have replaced the multi-function turn signal switch and the problem continues. Any suggestions what is wrong?


With intermittent issues, you have to test when problem is ongoing. These issues can be a pain to track.
There is a hazard switch separate from the multifunction switch. There are separate turn signal and hazard fuses, not only check the fuses, check the fuse circuit for voltage. Use a testlight to check voltage.
Use a wiring diagram, check proper color voltage wires to and from hazard switch, to and from turn switch when problem is ongoing. I can only help you with testing.

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.

I have an 02 kia sportage. my signal lights come on but dont blink outside. no lights for the signal lights come on on the dash at all. also, no hazard lights.


If the 15A HAZARD fuse in the passenger compartment fuse box is OK, power is getting to the hazard function of the flasher unit. Pressing the hzard switch should cause the hazard lights to flash. HOWEVER, there is an electronic time and warning indication system module connected to to the hazard switch lead and that may be affecting things. If the 10A TURN fuse is OK, power is applied to the turn switch (with the engine in START or RUN) and you state you can select a right or left turn. HOWEVER, the RED/WHT and RED/BLU outputs from the flasher unit connect directly to the front and rear turn lamps and the instrument cluster turn indicators so you are not getting any flasher output. Again, that electronic time & warning indication system module could be affecting things

Where is the flasher relay on a 2002 monte carlo


It's part of the hazard switch. have to take trim panel off to replace it .Apply the parking brake.
If the vehicle is equipped with a column shift, position the transaxle shift control indicator to 1.
Adjust the steering wheel for access.
Using a small, flat-bladed tool, gently remove the bezel from the ignition lock cylinder.
For the Impala, remove the right and the left access covers from the instrument panel (IP) fuse block.
For the Monte Carlo, remove the left access cover from the IP fuse block.
Remove the steering column filler. Refer to Steering Column Opening Filler Replacement .
For the Monte Carlo, open the instrument panel compartment door.
Remove the trim plate screws from the IP cluster.
Start at the left side of the IP cluster trim plate. Grasp the trim plate and carefully pull rearward. Disengage the IP cluster trim plate in order to easily access the hazard warning switch
Disconnect the electrical connectors from the hazard warning switch.
Remove the hazard warning switch from the IP cluster trim plate.

Turn signal not working


Press the Hazard switch on and check the turn indicator lamps. Replace the faulty lamps.
If the hazard lights do not work then the trafficator flash can is faulty provided the trafficator fuse is OK.
Check the fuse for the turn indicators, if it is blown the replace the fuse.

if the emergency lights are working the we can eliminate the relay because it's a combination relay for both turn signal and hazardous lights. you need to check the fuses, it's more likely the problem. it won't hurt to make sure if the bulbs are ok

My indicators and hazard warning lights have both suddenly stopped working have checked all fuses all seem ok


I think there is an issue with turn signal switch, test the leads at the switch that are supposed to have power, if they are ok replace the switch. An inexpensive test light will do nicely for these checks.
