Turning signal and 4-way hazard flasher not working

The turning signals and the 4-way flasher do not work. The 10 amp fuse looks fine; and, when changed with a new one still did not work. Where do I go from here?

    I also have a 2000 Toyota Sienna on which the the turn signal and hazard flashers are not working. We hauled out the Haynes manual (which is less than helpful in this case) and tried replacing the flasher relay switch. It's not that (although that is the most logical since whatever is going it effecting both the hazard and turn signal). It's also not the least so far as we can tell. We checked out the fuse near the relay and also tried to check out the fuse box in the engine compartment...but good luck trying to decipher the little codes on the fuse box map. We just ended up checking them all. Not that. So we are almost to the point of taking the dratted thing into the dealership - which will just kill me. Any ideas?

    Same problem here...turn signals do not work, nor does the hazard flasher. Checked all of the fuzes--and I do mean ALL. Thanks in advance for any solutions...

    I got the same problem., turn signal and hazard does not work. 10 amp fuse is ok. I need a solution. Thanks.

    I had the same problem and Silver top's suggestion worked for me. Thanks Silver Top.

  • Austengirl17 May 11, 2010

    Thanks for the suggestion silver top. You'll be happy to know that you are exactly correct - that's what was wrong - it was the "other" relay - which, of course, the Haynes manual didn't mention. Sigh. We found this out by taking it to the dealership and $175 later. At least they gave us a full refund on the incorrect relay switch part that we had bought. Hopefully, this will help some other folks. Thanks anyway :-)

The fuse for the flashers is in the cabin, below the steering column (left) and behind the ashtray. It is the top right spot.
It's a 7.5 amp fuse.

    My problem is that I think the wire is grounding out (the new fuses blow instantly and there were recently mice in the cabin). I bought the Chiltondiy online and there is NOTHING on which stinkin' wire to replace/repair.

    Can anyone tell me how to locate and check the wiring?

I have the same problem. Replaced the flasher but nothing. I see other relays but neither the Haynes or owners manuals don't mention them. Which is the other relay?

Problems with 2004 GMC Sierra Z71 left turn signal

The turn signal / hazard flasher module is the problem ,more then likely . Without testing this is just a guess . Do you know how to do automotive electrical circuit testing using a wiring diagram an a DVOM - digital volt ohm meter . Plus factory service repair manual flow charts .
The IGN E 10-amp fuse in the underhood fuse block supplies battery positive voltage to the turn signal/hazard switch assembly. The FLASH 25-amp fuse in the instrument panel (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-amp 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 driver door module (DDM)/passenger door module (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.

I have a 1990 dodge shadow I replaced the turn signal ***.& the flasher ,bulbs & fuse I have flashers but no turn signal I am stumped

i assume you mean that you have hazard flashers work and not the signals.there are two flasher units on the is for the hazards and the other is for the turn signals.they look exactly the same but have there own sounds like you changed the hazard flasher thinking it was the signal need to look for the flasher unit and change should be on the fuse panel or under the dash in the same general area.

1997 Chevy Tahoe both turn signals stopped working

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

1990 buick lesabre turn signals don't work,hazard flashers work, bulbs are ok, running lights & brake lights work, just installed a new turn signal assembly, thought that would fix the problem, it did...

I think that your flasher is bad I believe that the 4-ways flasher is a seperate flasher unit it should be in the fuse box and look like the 4-way flasher , to find the flasher turn on the 4-ways and you can feel it or hear it flashing and lok for the flasher for the turn signals

Turn signals wont work but flashers do

On your 98 Dakota.
Is equipaded with a single Flasher.
If you replace all ready.
Check the FUSE # 10, 15 amp..
On the Fuse box. left side of Dash.
and the FUSE D 25, amp. On engine compartment Fuse box.
Check the proper funtion of the HAZARD switch.
Bacause if the Hazard switch is bad the turn signal don't will work. Match the OLD flasher with the New one.

If after of this still not work.
Remove the steering wheel cover, locate the Turn signal switch connector and with a TEST Light check power with the Key ON
12v. to the RED wire and PINK wire..
If you found 12v. check the connection with the switch.
If the connection is good. you will need to replace the turn signal switch.
But if you don't found 12v. You need to look a an open circuit.
And fix it..

I hope this help on your problem..
Thank you for use fixya...
