Unable to locate the flasher for Hazard/Turn signals
Left turn signals (front and rear) and left hazard light do not come on. Right side is fine. All fuses checked, all bulbs checked. No one (auto parts stores) seems to know where the flasher relay is, or which it is. I've even replaced the turn signal arm to no avail. I need to know if the turn signals go through the hazard relay, and if so, where is it located exactly?
No , it's actually easy ! Just need the right tool ! You first need to pull the radio . This is where you need the dim pins there called . should have four holes ,two on both sides of the radio .That is where you stick this pins.then after you get the radio out there are four screws,thake those out ,then plastic trim piece just pulls off ! Three clips hold it !No , it's actually easy ! Just need the right tool ! You first need to pull the radio .

Re: Unable to locate the flasher for Hazard/Turn signals
Its part of the hazard flasher switch , or should I say the switch is part of it ! Where is your flasher switch located ? In the radio bezel ? the trim plate around the radio if you don't know what a bezel is . Oh yea , to answer you question , yes turn signals do go through it !
it's above the stereo, I assume on the bezel. Not easy to get out I'm guessing. lolit's above the stereo, I assume on the bezel. Not easy to get out I'm guessing. lol

Turn Signal Lamps
Ignition positive voltage from the HAZT/SIG fuse 15 in the instrument panel fuse block is supplied to the hazard warning switch. The turn signal lamps may only be activated with the ignition switch in the ON or ACCY position. When the turn signal switch is placed in either the left or right position, the flasher module sends an ON/OFF voltage to the turn signal switch assembly. For the rear turn lamps, battery voltage is applied directly to either the left or right turn signal lamps. The ground for the rear turn lamps is supplied from G401. For the front turn lamps, battery positive voltage is applied from the turn signal switch to the instrument panel electrical center. From the instrument panel fuse block, battery positive voltage is applied to the instrument cluster (IC) indicators and to the normally-open switched side of either the DRL L or DRL R relay, depending on the turn signal switch position. Battery positive voltage is then applied to either the left or right turn signal lamps. The front turn signals are grounded at G102.
For the hazard lamps, voltage is applied from the STP HAZ fuse 8 to the hazard warning switch. When the hazard switch is pressed, all the turn signal lamps will flash, including both IPC turn signal indicators. The hazard warning switch is grounded at G201.
Your best bet , take it to a qualified repair shop.
Turn Signal Lamps
Ground is applied at all times at G200 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 circuit. Battery voltage is applied at all times to the BCM. The BCM then applies a pulsating voltage to the front and rear turn signal lamps. Ground for the left front turn signal lamp is supplied at G101. Ground for the right front turn signal lamp is supplied at G102. The left rear turn signal lamps are supplied ground at G402 and the right rear turn signal is grounded at G401.
Hazard Flasher Lamps
The hazard flashers may be activated in any power mode. The hazard switch is located on the radio/HVAC control panel and is permanently grounded through G402. When the hazard switch is placed in the ON position, ground is applied through the hazard switch signal circuit to the body control module (BCM). The BCM supplies battery voltage to all four turn signal lamps in an ON and OFF duty cycle. When the hazard switch is activated, the BCM sends a serial data message to the instrument panel cluster (IPC) requesting both turn signal indicators to be cycled ON and OFF.
There is no flasher fuse . Main power fuse's for the BCM - if one of these were blown you would have more then just the flashers not working .
Your best bet , take it to a qualified repair shop.
Generally speaking, symptoms of a bad or failing turn signal bulb are usually the culprit...in your case, either it's the front left or rear bulb. Varies for different vehicle makes...common signs include:
turn signal light staying on solid
or blinking very fast
or either sides of the bulbs stop blinking altogether.
To test this, make sure you reconnect everything you disconnected.
Turn the left signal light on; go to the front of the vehicle, is the turn signal bulb illuminated? If it lights up, even though it is not blinking obviously the bulb is okay. If it doesn't, replace it- problem solved. You'll do the same procedure for the rear turn signal Is that lit up? If not replace the bulb and the problem is solved.
Another common failure is when the turn signal blinks really fast, same procedure as mentioned above.
If both bulbs for the left side and right side illuminate but don't blink, the problem is in the steering column turn signal switch.
If the left or right side blinkers don't work properly at all...then check the integrated hazard warning/turn signal flasher relay- that may be defective; again, that's usually the case if both sides of the signal light don't work.
If you are blowing any fuses related to the flasher system, you have an electrical overload in the turn signal circuitry.
In my case the left front turn indicator lamp worked, but not the left rear indicator, although all the lamps would turn on with running lights activated, as well as the backup light and 'night-light' mode. The left rear turn indicator would not work with the hazard lights activated. I tested the combination switch (this is the left/right turn indicator switch you use when driving to indicate which direction you are going and is mounted/located on the steering column) and it tested O.K.. I had good continuity from the combination switch black wire, and resistance on the blue-white wire from there to the left rear turn indicator lamp, as well as good continuity on all wires going out from the left parking light fuse. Since the Haynes manual indicated that the flasher module was probably good if it made the tell-tale clicking sound, I was feeling perplexed. So I took it into a local shop that specialized in auto electrics and it turned out to be the flasher module. I was under the impression that it operated in a straight-forward left-right manner, but apparently it has a different circuit for each turn indicator lamp. So even if it is making the appropriate clicking sound when the combo switch is flipped, it could still be the flasher module. Obviously the manual leaves a bit to be desired in the troubleshooting of malfunctioning turn indicators.
assuming you have check both front and rear signal lights and they are working then it sounds like the signal flasher is not working for the left side only.put on the hazard flashers to check bulb operation and if the bulbs work then the only thing in the system is the turn signal flasher not working for the left side.the signal flasher looks the same as the hazards but is a different flasher located in the same area as the hazard.

Turn Lamps
Voltage is applied through the TURN fuse and the turn/hazard flasher when the ignition switch is in the following positions:
• RUN
• BULB TEST
• START
The voltage travels to the contact in the hazard switch. The hazard switch is located in the turn/hazard-headlamp switch assembly. This contact is normally closed.
When the left turn signal is turned on, voltage is applied to the following components.
• The left turn indicator
• The left front park/turn lamp circuit 14
• The left rear turn lamp circuit 18
The turn lamps turn on immediately. The current flow heats up the timing element. The timing element is located in the turn/hazard flasher. The timing element repeatedly opens and closes the circuit. This action causes the turn lamps to begin flashing.
The voltage that is applied to the left front park/turn lamp is also applied to the left front marker lamp. If the headlamp switch is in the OFF position, the left front marker lamp will find a path to ground through one of the following lamps. The following lamps provide low resistance paths to ground:
• The right front marker lamp
• The right turn indicator
• The right front park/turn lamps
• The left front park/turn lamps
The left front marker lamp flashes with the turn lamps. The voltage drop across the marker lamp is much higher than the voltage drop across the other lamps. The lamps that are used for the ground path will not flash.
When the headlamp switch is in either the PARK or HEAD positions, voltage is applied through the following components:
• The EXT LP fuse
• The marker lamps
• The park lamps
When the left turn signal is turned on, the left marker lamp will have voltage at both connections. The left marker lamp does not light. When the turn/hazard flasher stops the voltage to the turn lamps, the marker lamp is grounded through the turn lamp. The marker lamp does not go on. The left front marker lamp flashes in the following manner:
• The left front marker lamp flashes on when the turn filament of the left front park/turn lamp goes off.
• The left front marker lamp flashes off when the turn filament of the left front park/turn lamp goes on.
Voltage is applied to the right lamps in the same manner, when the right turn signal is turned on.
Hazard Lamps
Voltage is applied at all times through the following components to the normally open contact of the hazard switch in the turn/hazard-headlamp switch assembly:
• The STOP HAZ fuse
• The turn/hazard flasher
When the hazard switch is turned on, voltage is applied to the following components:
• The front turn lamps
• The rear turn lamps
The following lamps flash on and off:
• All of the turn lamps
• Both of the turn indicators
The front marker lamps flash with the hazard lamps on, just as the front marker lamps flash when the turn lamps are on. If the headlamp switch is in the OFF position, the front marker lamps flash on when the hazard lamps are on. The front marker lights will flash on when the hazard lamps are on if the headlamp switch is in one of the following positions:
• PARK
• HEAD
When the hazard lamps are on, the following conditions apply:
• The turn circuit is always open.
• The turn/hazard flasher controls the lamp.
Park/Marker Lamps
Voltage is applied through the EXT LP fuse, to the headlamp switch at all times. Voltage is applied to the park lamps and the marker lamps when the headlamp switch is in the following positions:
• PARK
• HEAD
The front marker lamps are grounded through the turn filament of the respective front park/turn lamp. The front marker lamps light as a result.
Stop Lamps
Voltage is applied through the STOP HAZ fuse to the brake switch at all times. When the brake pedal is depressed, the brake switch closes. This action applies voltage through the turn/hazard-headlamp switch assembly to the following lamps:
• The high mounted stop lamp assembly
• The left tail/stop-turn lamps
• The right tail/stop-turn lamps

What may have happened is either the headlights wiring or the parking lights wiring somewhere along the wiring fused to the left turn signals wiring. Depending on if the turn signals go on when you put the parking lights on or the headlights on.
If the signals come on when you turn on the headlights than you only need to locate the light green wire that comes off the left turn signal harness.
Next follow that wire the entire way back to the firewall looking for another wire fused to that wire as you go.
If there are no signs of this you need to continue looking on the other side of the firewall all the way back to the turn signal and hazard flasher unit which is a black box that connects to a black harness located next to a grey harness behind the knee bolster.
But if the signals come on when you turn on the parking lights than you will also need to check the wiring from the rear left signal and follow that light green wire all the way back to the turn signal and hazard flasher unit.
This should fix your problem, but if not than your problem may lay within the the wiring between the turn signal/hazard switches and the turn signal and hazard flasher unit.
Also you may have a burnt circuit in the junction block. This block is where the light green from the rear left signal and front left signal meet. Don't have a description but if you cannot find it let me know and I will go out to the yard and look myself and let you know.
Just above the stereo on the bezel, I'm assuming. Not easy to get to
No , it's actually easy ! Just need the right tool ! You first need to pull the radio . This is where you need the dim pins there called . should have four holes ,two on both sides of the radio .That is where you stick this pins.then after you get the radio out there are four screws,thake those out ,then plastic trim piece just pulls off ! Three clips hold it !
