Turn signals Left turn signal turns on flashers. Even with the key off and out of the ignition. Replaced Multi switch and combination flasher. After flasher was replaced it worked fine for about a week. Then the flasher thing started. Flashers work fine, right turn signal works fine.

I have 2000 chev blazer , and every time I start the car, I hear the turn signal making tik- tak sound even though I have not turn signal on. The signal switch works ok , and it returns back to the normal position , but that tiking drives me crazy, it stops only when I apply breaks, and when I let the brakes off, it starts to make that sound. Can anyone help?

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 .

I have replaced the flasher relay on my 2004 GMC Sierra but the hazard and signals still do nt work


Looking at the schematic diagram for the system(s), the flasher module is the first and only component common to the turn signals and hazard flashers, Unless the replacement module is bad, then there are only two possibilities: Both the Left and Right Turn Fuses in the left instrument panel fuse block are blown, or you have a ground problem from the flasher module.

Where is the emergency flasher relay located on 2013 Rogue?


Here is what the service manual says. Looks like it is not a flasher relay but a function of the body control module.

TURN SIGNAL AND HAZARD WARNING LAMP SYSTEMSystem Description OUTLINE Turn signal lamp and the hazard warning lamp is controlled by combination switch reading function and the flasher control function of BCM.
TURN SIGNAL LAMP OPERATION - BCM detects the combination switch condition by the combination switch reading function. - BCM supplies voltage to the right (left) turn signal lamp circuit when the ignition switch is turned ON and the turn signal switch is in the right (left) position. BCM blinks the turn signal lamp.
HAZARD WARNING LAMP OPERATION BCM supplies voltage to both turn signal lamp circuit when the hazard switch is turned ON. BCM blinks the hazard warning lamp.
TURN SIGNAL INDICATOR LAMP AND TURN SIGNAL SOUND OPERATION - BCM transmits the turn indicator signal to the combination meter with CAN communication while the turn signal lamp and the hazard warning lamp are operating. - Combination meter outputs the turn signal sound with the integrated buzzer while blinking the turn signal indicator lamp according to the turn indicator signal.
HIGH FLASHER OPERATION (FAIL-SAFE) - BCM detects the turn signal lamp circuit status by the terminal current value. - BCM increases the turn signal lamp blinking speed if the bulb or harness open is detected with the turn signal lamp operating. NOTE: The blinking speed is normal while operating the hazard warning lamp.

Turn lights blink with hazards but not with turn signal..flasher replaced. is It the multifunction lever then??


There should be a turn signal flasher and a hazard flasher. They are two different parts. If you replaced the hazard flasher and not the turn signal flasher than I would start by replacing the turn signal flasher.

One thing you can do once you find the turn signal flasher is to unplug it and use a jumper wire between the two pins of the connector then turn the key to the run position and place the turn signal lever in the left or right position. If the turn signal lights know light up than the turn signal flasher is the problem

Left turn signal lights are not working


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.

My signal give clicking even when it is not on,it signals when click it right or left,but when it return to neutral it start clicking n faster.


The most common cause of this is a bad turn signal switch. The switch is grounding the supply wire from the flasher which makes the flasher think the switch is in a turn position. Since there is very little load on the grounded circuit the flasher "clicks" faster.

A new turn signal multi function switch will usually fix this problem.

Where is the turn signal relay located


Hi Bernard:
The FLASHER is located under the driver dash it is a round fuse (it's located adjecent to the fuse block, and it's square, yellow in color).

Also, I suggtes to check for power at the junction box under the dash at terminals 1 and 6 with the combination flasher removed. Then check with a powered test lamp if test lamp lights pin 7 when signaling left and pin 8 when signaling to the right.

If the test results are correct, replace the Combination Flasher/DRL (Daytime Running Lights) module.

Gain access to the multifunction switch connector. Locate the Light Blue/Yellow wire and ground it. This should activate the right side turn signals. Locate the Light Blue/White wire and ground it. This should activate the left side turn signals. If both sides do work, the problem is in the multifunction switch. Verify the Black wire in the same connector is grounded at all times. If so, replace the multifunction switch.

Here is some reading on how the system works.

ELECTRONIC DAYTIME RUNNING LIGHT (DRL)
The Combination Flasher/DRL is a module providing turn signal, hazard warning, and daytime running light functions (for Canadian vehicles), and has been designed with internal relays to take advantage of low current switching requirements in the vehicle. It is plugged into the junction block at positions three and four, where all wiring associated with its operation is terminated. The junction block is adjacent to and left of the steering column of the vehicle.

On vehicles built for use in the United States, only position four is used. Vehicles built for use in Canada utilize both positions three and four.

To gain access to the device, remove the lower steering column cover and knee blocker.

The combination-flasher/DRL may be operated in its hazard warning mode either with or without the ignition circuit being active. However, in order to operate in the turn signal mode or the DRL mode, the ignition circuit must be completed to the module.

While the combination-flasher portion is idle, there is no current drawn through the module. The device does not become active in the turn signal or hazard warning modes until a signal ground circuit is supplied to either of the turn signal inputs or the hazard warning input. With the ignition OFF, there is no current drawn through the module.

While the ignition is ON, the front turn signal filaments are illuminated steadily thus providing the DRL function. The DRL function may be inhibited by applying a signal ground input from either the park brake circuit or the headlamp relay activation circuit.

Hope this helps; also keep in mind that your feedback is important and I will appreciate your time and consideration if you leave some testimonial comment about this answer.

Thank you for using FixYa, have a nice day.

Left and right signals wont work any ideas?


Have you been checking for voltage with a voltmeter? If not, that would be good to do. But first, have you checked fuse F1 in the power distribution center under the hood? It is 20 amp and next to the fuel pump relay. Check to see that it shows voltage on both sides of the fuse. That is the feed for the hazard flasher and if it is working and you replaced the combo flasher, then I would believe that the hazard flasher part of the combination switch is bad. I don't see a hazard flasher relay in that underhood box, please describe it.

Have you checked for voltage on fuse #3 behind the dash when the ignition is in the run position? If you have that, and you replaced the combo flasher then I would suspect the turn signal part of the combination switch is bad. The "backbone" of the combo switch services both the hazards and the turns. If that were faulty or corroded, then both kinds of lights would not work. Try spraying some electronic circuit cleaner in that switch to possibly clean up the internal contacts. I can give you the continuity tests for the pins of that switch if you have either an ohmmeter or a continuity checker.

Have you removed the steering column covers (after removing the tilt lever) to check that the plug into that multi-function switch is seated firmly in its socket?
