Take the panel under the steering wheel off and its behind a little lip on the right side (left side of the stereo)

Its real easy to get too after you take that panel off.

My signal flasher does not work, the lamp light straight away, not blinking.


Depending on the vehicle, a flasher module may be located on or near the fuse box for the light circuits. Check you manual for the location of the fuse box(es) and the directory for a flasher.

Hasards dont come on on a 2000 isuzu trooper


No need to panic-this can SEEM TO be caused by a couple of things, but it is fairly simple to determine exactly what is causing this flasher circuit condition.
First, turn on your flashers, however you have to do it, and walk around the truck to check that all bulbs are working (at least one on each corner). Turn signal and hazard flasher relays are thermal circuit interrupters and are current sensitive and will not work properly with too few or too many bulbs in the circuit. (This is usually a big problem when switching over to LED lamps, as LEDs only draw a fraction of the current that the bulbs do. This causes the relay to either not flash at all or flash very fast and triggers warning circuits on newer cars) If there is one or more bulbs out, they must be replaced.
That being said, I doubt that alone is your problem. Here is a general automotive wiring primer aimed at the turn signal, hazard, stop, and running lights on most all motor vehicles.
Hazard flashers are required by D.O.T. safety standards on all motor vehicles that may ever be used anywhere near a public road. They are also required to be able to be used without the ignition key. This means the flasher circuit for hazards is fed thru a fuse that connects straight to the battery and is energized at all times.
Turn signal circuits often share the same flasher relay as the Hazards, even though the power for them is switched through the ignition key. Power for directional blinkers connects to a fuse, then the ignition switch, then to the battery.
So, if you have to turn on the turn signals (is the key on?) to get hazards to work, that means they are not getting power direct from the battery, but can get it when the turn signals are on because they both use the same relay. This is usually the case on all vehicles; If 4-way flashers and turn signal are both on at once, the 4-ways override the turn signal and force all signal bulbs to flash. The turn signal never forces one side of the hazards to stop blinking.
So, where does that leave us? You simply have a blown fuse, my friend. The hazard lamps fuse may also power the cigarette lighter, dome light, or other "always on" accessories. This varies with make & model, but the Hazard Lps fuse is usually well marked in the fusebox. If the fuse blows again shortly after being installed, do not put in a larger one! Try one more. If it also blows immediately, there is a problem with the wiring, or a bulb could be in wrong and shorting to the socket ground. Try removing all the flasher bulbs and trying the switch(it won't flash or "tick-tock") again. If the fuse does not blow, you have found the problem. Good hunting!

1998 Dodge Durango flasher relays location


Turn on the Durango and check each of the four turn signals to make sure that the bulbs are not burned out. If you find one that has gone out, replace the bulb and retest the turn signals. When a bulb goes bad on this circuit, the resulting operation can mimic a bad flasher or one that is failing.

Locate the combination turn signal flasher and relay. It is on the left end of the driver's dash. Open the access door and view the collection of relays and fuses. At the left side of the mounting block is a larger flasher and relay. This is the combination turn signal flasher and relay.

Test the relay by placing you finger on the relay housing and activating the turn signal. If you have found the right one, you should feel a clicking as the turn signal blinks. Remove the relay, replace with the new relay and close the access door

.

Start the Durango and activate the turn signals to check that they each work. The light should turn on and should blink. Also, check the hazard lights to make sure they work.

Both my right & left turn signals aren't working but hazards are


If you can locate the hazrd flasher unit under the dash on the drivers side, the turn flasher unit should be right beside it and looks the same. Unplug and switch the 2 flashers and see if the turn signals work. The flasher unit is a silver and round. they are usually close to the stering colum. Let me know if that helps.

Where is the turn signal flasher unit found on a 2001 Chrysler Concord


COMBINATION FLASHER LOCATION The Turn Signal and Hazard Warning Flasher is combined into one unit called a Combination Flasher (Combo-Flasher) The combo-flasher controls the flashing of the hazard warning system and the turn signal system. An inoperative bulb or incomplete turn signal circuit will result in an increase in flasher speed.
The combo-flasher is mounted to the in-line bracket which is located to the right of the Junction Block. The flasher can be removed by pulling in an rearward direction. The left under panel silencer duct must be removed to access the flasher. The combo-flasher is black in color for ease of identification

My turn signal lights are no longer working, bulbs seem fine. whats the problem?


If none of your turn signals are working, try pushing in the hazard flasher button on your car, to see if all four lights flash. If not, you need to first locate the fuse to the flasher circuit, and if it is good, locate the flasher unit. It is usually located near or plugged into the fuse panel.

Turn Signal Fuse or switch replacement? '93 buick lesabre?


Yes all the wiring needs to be complete. Then all the bulbs must be inserted into sockets. left side marker right side front turn back turn reverse lights brake light everything. Then make sure they all work. The problem could even be a bulb thats on the fritz ready to blow but still on and dim little light. if that's all fine then it's probably your flasher. There are 2 flashers one for turn and one for hazards but I think they are the same but still separate. located under dash on either side of the steering wheel. The flasher closest to the door is up in there pretty far it's size is about like a 2 liter cap and it's silver. good luck

1997 Chevy Tahoe both turn signals stopped working


Sounds like the flasher unit to me. Normally the emergency flasher and turn signal are separate.

2000 toyota camry turn signals not working. Fuses check out and bulbs good.


Hi, i recommend testing the switch and flasher module. i will post the testing procedures for both devices. replace the device that is faulty.

To test turn signal switches, use a 12-volt test light to probe for voltage into and out of the switch. The ignition switch must be in the RUN position for the circuit to operate. If voltage is present on the input side of the switch but not on the output side, the switch is faulty.

FLASHER TEST PROCEDURE---
  • A test light can be used to determine which flasher is used for the turn signals and which is used for the hazard warning light.
  • An easier way is to turn on both the directionals and the hazards. This activates both flasher units.
  • By removing one of the flashers, the affected circuit no longer flashes.
  • Therefore, that flash unit controls that particular circuit.
  • If the turn signals fail to operate and the fuse is good, the flasher has probably failed.
  • Occasionally, the flasher does not flash as fast as it once did, or it flashes faster. This is also cause for replacement.
  • If it flashes too slowly or not at all, check for a burned-out bulb first.
the flasher is located in the Front seating area, driver side, driver side of steering column, mounted in corner behind instrument panel

If the turn signals operate properly in one direction but do not flash in the other, the problem is not in the flasher unit. A burned-out lamp filament will not cause enough current to flow to heat the bimetallic strip sufficiently to cause it to open. Thus the lights do not flash. Locate the faulty bulb and replace it.
