the turn signals on my friends 02 xterra stopped working.. checked all the fuses in the car and under the hood and it seems ok. also the hazards are not working. has anyone else experienced this? i'm leaning towards a the switch being bad. i'm new to working on nissans and firgured this would be a good source for some tech help.. the dealers answer is to "bring it in"
thanks, Pat.

Pat, well welcome to the site (sort of). My first guess would have been a fuse. I'll have to check my '02 Service manual when I get a chance and see what I can find. Maybe the multi-function switch on the steering column is acting up.

Your hazard fuse is blown, or the hazard switch is not connected to the plug

Welcome to the club!

FYI, none of your blinkers will work if the hazard are not working

-James

is there a relay for the turn/hazard lights i if so it could be out..... i will look at the manual today and post info on it tonight.....

Hope this helps. I'd guess it's your combination flasher unit. Supplies both hazards and turn. Find the flasher and check it for power and ground. With the ignition in the on position, the white wire w/ green stripe going to the flasher should have power. The black wire should be connected to ground. If these conditions are met, than there's nothing wrong with the fuses, or the hazard switch. If it was the turn signal switch, then your hazards should still work, so I'm betting that's not it. It could be a bad connection or faulty hazard switch, but power at the flasher would eliminate that.

-James I disagree, to a point. Just went through this today with my X, turn signals worked fine with a blown hazard fuse. You can see that there are two separate fuses supplying the flasher. One feeds straight through the hazard switch and supplies the turn signals. If you flip on the hazards, it removes that power source, and connect to the hazard fuse. So the 10A hazard fuse is just for hazards, and the 7.5A turn signal fuse is just for the turn signals. However, you are correct that the turn signals won't work if the hazard switch is disconnected, cause you'll lose that power feedthrough to the flasher.

Why don't you try being helpful????;)

Thanks for the great info!

I have a question though, If your hazards are not plugged in, will your blinkers work? Nope!!! I am just wanting him to start with the easiest thing first.

I just completed the Manual-AC-Compressor-in-Defrost-Mode Mod at lunch.
I plugged the hazard switch connector back up (I'm headed back out to double check).

Problem: Turn Signals stopped working.
Hazards work fine.
headlights work fine.
Turn Signal fuse is fine (7.5A under dash)

Any suggestions?
(And please do not mention blinker fluid)

thanks

Just double checked the hazard hook up. It's fine.
Even swapped out the Turn Signal fuse. No luck.

I'm guessing blinker for turn signals.
Anyone know right off where it is located?
Sounds like it's behind the guage cluster... but can't tell.

thanks

Wow, thank you so much. Your info was very helpful:anbeten-big:

ok,, so this thread has not been posted on in while, but I am hoping someone might be able to help. My turn signals and emergency lights have not been working for over a year and it is really now becoming a PAIN in my A**.

- I have checked fuse #2, & #17 and both are perfectly fine, have swapped them with others, just in case with no luck.
- I bought a relay from Ebay matching the same # as the flasher relay(goes underneath the dash by the steering column), because someone had mentioned this could be it, but it still does not work. It was not a new relay, but supposively a tested one that was ok, and made no difference in my truck.

I went to an electritian, he did not even look at it, but said that most likely it was the steering column turn signal switch, that was acting up and that I would need a new one. Didnt even want to look at it, unless I bought a new switch. I can imagine this being a reason why the turn signal does not work but also the emergency lights?

My truck did not come with fog lights, so I bought the factory ones from courtesy parts and got a new steering column switch, that also had the fog light switch (My X was prewired for fog lights so it was very easy to install),,,

I would normally just get my old column switch (before the fog lights), and try swapping it out to see if this really could be it, but I cannot find it any freaking where... I have searched this house upside down with no luck!!!! I really dont want to buy a new steering column switch UNLESS I really DO need it (and not like with the flasher relay).

Does anyone have any more insight into this??????? When it started it was only the blinkers and then also the emergency lights, someontimes they would work and sometimes they wouldnt, now they wont at all.

Crazy thing is my keyless works, (lights flashing), brake lights work, running lights work...

Please any help wooould be greatly appreciated... and sorry for the ranting,,, I really just wanted to give as much detail as possible.

Oh, also, thought I would mention since everything is on the same steering column switch.... that my headlights and fog lights both work great!!... (knock on wood)

ok another post sorry,,, everything keeps pointing back to the flasher relay by the steering column,,, but since I was too cheap , i did not buy a new one,,, ,, is there another relay somewhere easy to get to,, so I could try that?
