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.

The fuse for a right turn signal on a 2001 Buick Park Avenue


The left an right turn signals get there power from same fuse ,HZDT/SG fuse 15amp in the left under hood fuse box. through the turn signal hazard flasher module. Here is how they work .
Turn Signal/Cornering Lamps
The HZDT/SIG fuse in the fuse block - underhood - left supplies battery positive voltage to the turn signal/hazard flasher module and have ground at G202. The turn signal lamps may only be activated with the ignition switch in the ON or ACCY position. The T/SIG fuse in the fuse block - underhood - left supplies battery positive voltage to the turn signal switch. When the turn signal switch is placed in either the left or right position, current flow is from the turn signal switch assembly to the turn signal/hazard flasher module. The turn signal/hazard flasher module then sends an on-off voltage signal to either the left or right turn signals and their instrument cluster (IPC) indicator. When the hazard switch is pressed, all the turn signal lamps will flash including both IPC turn signal indicators. The left turn signals have ground at G106, G400 and at G402. The right turn signals have ground at G105 and G400. The turn signal switch supplies battery positive voltage to the cornering lamps, the left cornering lamp has ground at G105 and the right cornering lamp has ground at G106.The turn signal switch or the turn / hazard flasher module is bad or there is a wiring problem. Go to you tube an check out a few videos on basic electrical testing ,then get a DVOM - digital volt ohm meter , an wiring diagram an trouble shoot the circuit . There may even be a video on test turn signal circuit .

Passenger side turn signal flashes faster but dont work even at day runing light, comes on when head lights are on, replace bulb and socket because was melted but stilldoes the same


Turn Signal Lamps
The turn signal lamps may only be activated with the ignition switch in RUN or BULB TEST position. The T/SIG fuse supplies ignition voltage to the turn signal switch. When the turn signal switch is placed in either the left or right position, the turn signal switch sends an ignition voltage to the hazard lamp/turn signal flasher, which sends an on-off signal to the turn signal switch. When the turn signal switch receives the on-off signal it will send that signal to the following lamps on the LH or RH side:
?€¢
The Rear Turn Lamp


?€¢
The Turn Signal Indicator


?€¢
The Sidemarker Lamp


?€¢
The Sideview Mirror (Pontiac Thunder only)

The turn signal switch also sends a separate on-off signal to the Daytime Running Lamps (DRL) control module, which relays the signal to the appropriate front turn signal. The front turn signals are grounded at G101 and G102. The rear turn signals are grounded at G401. The sidemarker lamps are grounded through the corresponding front parklamp.
The sideview mirror turn signals are a bank of LEDs placed behind the mirror glass.
The hazard lamps operate on battery voltage. The HAZARD fuse supplies battery voltage to the turn signal switch. When the hazard switch is pressed, the turn signal switch sends battery voltage to the hazard lamp/turn signal flasher, which sends an on-off signal to the turn signal switch. The turn signal switch send the on-off signal to all the turn signal lamps, causing all the lamps to flash including both IPC turn signal indicators. The hazard lamp/turn signal flasher is grounded at G200.
When the parklamps are ON, the sidemarker lamps receive voltage from the park lamp supply voltage circuit and illuminate. The sidemarker lamp is grounded through the corresponding rear turn signal. When the turn signal switch is place in the left or right hand position, the rear turn signal illuminates and the sidemarker lamp will loose its ground, causing the sidemarker lamp to turn off when the turn signals are on and to illuminate again when the turn signal is off.
Which blub an socket did you replace ? check the other blub ? The switch and or the flasher module can cause this problem .
Replace the turn signal switch. Refer to Multifunction, Turn Signal, and Hazard Switch Replacement - On Vehicle in Steering Wheel and Column.

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.?
2009 WK jeep
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.

2010 chevy equinox right rear turn signal doesnt work, replaced bulb and still the same. front works, is there a fuse for the rear light and where is the fuse located.


RT/SIG fuse #11 15amp - I/P fuse box . Fuse Block - I/P
In the center of the instrument panel, beneath the right side of the radio, in back of the right side console access panel.
This fuse is power to the BCM , When you put on the right turn signal , this is a voltage signal to the BCM . With logic ( programming ) the BCM then controls the turn signal !
Turn Signal/Hazard Lamps
The body control module (BCM) is responsible for controlling the turn signals and hazard lamps. When the turn signal switch is placed in either the left turn or right turn position, the BCM receives a signal from the turn signal switch. The BCM then sends an on-off voltage signal to either the left or right turn signals and their instrument panel cluster (IPC) indicator. When the hazard switch is pressed, the BCM receives a signal from the hazard switch. The BCM then will send an on-off voltage signal to all the turn signal lamps. All the turn signal lamps will flash including both IPC turn signal indicators.
There could be a DTC- diagnostic trouble code stored in the BCM pointing to the problem ! I suggest you take your vehicle to the dealer or a ASE certified repair shop that has the diagnostic tools to find the problem . Just so you don't waste your money replacing parts that don't fix it.

Lighting control module ? ?????? Hazard / flasher module ! Now ( there''s not even an electrical signal where the fuse plugs into the interior fuse panel.) What FUSE ??????

Stop Lamps
The STOP LP 25 A fuse in the underhood fuse block supplies battery positive voltage to the normally open stop lamp switch. When the driver presses the brake pedal, the switch contacts close and battery positive voltage is supplied to both the STOP 15 A fuse and the CHMSL 10 A fuse in the I/P fuse block, and to the turn signal/hazard module. The turn signal/hazard module then supplies voltage to both of the trailer rear turn/stop lamp supply voltage circuits. The voltage from the CHMSL 10 A fuse is to the center high mounted stop lamp (CHMSL) and the trailer jumper harness. The voltage from the STOP 15 A fuse is to the stop lamps, throttle actuator control (TAC) module, and the cruise control.
Backup Lamps
The backup lamp request signal is sent from the powertrain control module (PCM) to the body control module (BCM) on the Class 2 message system. This signal is based on the park neutral position (PNP) switch signal. The BCM supplies voltage on the backup lamp supply voltage circuit to the backup lamps and to the automatic day/night mirror. Voltage for the courtesy lamp supply voltage circuit and backup lamp supply voltage circuit is from the TBC B fuse in the instrument panel fuse block directly through the BCM to these circuits. A short to ground on either of these circuits will open the fuse. The backup lamps are grounded at G401.
For trailer wiring, a separate backup lamp circuit is connected through the underhood fuse block from the TRLR B/U 10 A fuse to the trailer wiring harness.
Turn Signal/Hazard Lamps
The IGN E 10 A fuse in the underhood fuse block supplies battery positive voltage to the turn signal/hazard switch assembly. The FLASH 25 A fuse in the I/P fuse block supplies battery positive voltage to the turn signal/flasher module and ground is supplied at G200. When the turn signal switch is placed in either the left or right position, a voltage signal is completed from the turn signal switch to the turn sign/flasher module. When the hazard flasher switch is activated, a ground signal is completed from the turn signal/hazard switch to the turn sign/flasher module. The turn sign/flasher module then sends an on-off voltage signal through the LT TRLR, RT TRLR, LT TURN or RT TURN 10 A fuses in the I/P fuse block to the appropriate turn signal or to all 4 fuses for hazard operation. The instrument panel cluster (IPC) indicators receive voltage from the LT TURN and RT TURN fuses as well as the DDM/PDM for the mirror turn signals. The DDM/PDM has no function or control of the mirror turn signals other that a pass through connection for the circuits. The audio chime is also activated when the turn signals are on. When the hazard switch is pressed, all turn signal lamps will flash including both IPC turn indicators. The front turn signals are grounded at G100. The rear turn signals are grounded at G401. The Mirror turn signals are grounded by the DDM/PDM.

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.
