Hazard warning switch

[Hendrik_GER]

For registration in Germany, the hazard warning lights must work. Unfortunately, the switch is defective. It doesn't lock into place. Even when I hold it down, the hazard warning lights don't work. Does anyone have experience with it and know what might be wrong? Otherwise, the lighting system works perfectly. I think I need the complete indicator switch unit, right?

Many thanks in advance. ☺️

Been awhile since I used the hazards but I think its a "pull" and will click to stay out, not a push

I think so too.

it's a pull.

It's a "pull out" knob, but if the little plastic tooth has worn out, you'll have to replace the whole unit.

Thanks for the quick help. ☺️ Then the button is permanently out, without the hazard lights working. I'll buy the part Scott posted. 👍

If you button is out and hazards are not flashing may also be the flasher mounted on the fuse panel . It is the hazards flasher the turn flasher is under the dash  around the radio area. It is a lot easier to replace but could also be the part Scott showed in his post. Good luck

Correct.

it is a pull out. Don't feel bad When I had the tilt column installed, I thought the same and had to be corrected.

Can you push the button in?

[Hendrik_GER]

I now have the turn signal switch, and it must be the case that the small groove on the switch is worn out, and the switch is no longer held in place. I can push the switch in, but it pops back out.

Otherwise, all the lights and indicators work without problems. Since the switch is permanently pulled and the hazard lights don't work, I think the relay is also defective or something was removed by the previous owner. I'll get to work on it this weekend.

You'll probably need a lock plate tool and probably steering wheel puller if you don't have one. While your in there check the screw on turn signal switch make sure its tight, they can loosen up over time. Just don't over tighten it.

Thank you very much for the info. 😊 I have all the necessary tools. Including the one for the steering wheel lock.

I recently reinstalled the original steering wheel. And then I discovered that the switch was defective. 🙈🤣

Murphy's Law....

Gets you every time.   

[Hendrik_GER]

I'm getting desperate right now. 🤣 The switch for the hazard warning lights works correctly again after the replacement, but the hazard warning lights don't work.  Does anyone have a tip? I also replaced the relay. No difference. Otherwise, everything works as it should, except for the hazard warning lights, which won't turn on.

The flasher on the fuse block is for the 4 way flasher did you change that?

[Hendrik_GER]

I'll check that. 👍😊

 

It's also the case that now that the Hazard switch is working again, the turning lights don't work when the hazard warning switch is engaged. The Turnus lights only work when I pull out the hazard warning switch. Something is being rewired. I'll check the fuse box.

[Scott S.]

Hazards and turn signals don't work at the same time.... The hazards cancel the turn signal.

But that should happen when the knob is pushed in. 

Sounds backwards to me. ????? 

[Hendrik_GER]

It's crazy. The turn signals only work when the hazard switch is pulled out. If it's pushed in, they no longer work. The hazard lights never work.
 

The previous owner had to change some wiring because the turn signal switch was defective (the hazard switch could no longer be pushed in).

Here is a wiring diagram I had to zoom in on the hazard system (top left corner)but this will help you do some quick testing. First thing is pull the hazard flasher from fuse block. One side of the two exposed terminals should have 12 volts the key will probably have to be in run position. If you don’t have 12 volts problem is between fuse and that terminal . Second If you do have power to the one terminal then with a dvom do a continuity test from the other terminal the one without any power to the what appears to be the brown wire on the harness side of the plug (top right of wiring diagram)where you just plugged in your new turn signal switch . You should have continuity . Third back to the terminal at the flasher with 12 volt's. That terminal feeds your stop lamp switch ( bottom middle of diagram) so you should have 12 volts there also on the tan wire. I am sure that is the case since you haven’t mentioned any problems with tail lights. Fourth on the stop light switch the white wire you could do a continuity test to the same harness plug where you plugged in your turn signal switch you should have continuity there also. Again I believe you will find that to be ok also. The most likely thing is going to be between flasher and turn signal plug. If not it has to be between turn signal plug and rear end. If needed could send that diagram. Hope this helps good luck

Thank you very much Greg. 😊 That helps 

[Scott S.]

Yes, it sounds like the previous owner got some wires crossed. 

Guess the colour coding didn't help him.
