Has anybody experienced this symptom - HAZARDS ONLY WORK WITH IGNITION ON?

What was your solution?

-MFS works will all the other functions, including directionals
-MFS connector is brand new - thus no shorts
-Fuses OK
-Front / Rear lighting system operational
-Yes, hazards work with ignition on but NOT off!

My guess is the part of the flasher relay that handles the hazards is shut.

Opinions?

Happy Holidays!

By chance who did the replacement connector, possible crossed wire? From all time hot to only when key on? I was looking at that nasty dragon when I replaced my switch a few weeks ago. Connector is coming apart from age and heat.

Hi Blade,

I replaced the connector. I checked once, twice, three times but anything is possible. I'll check it again after the New Year's but, I doubt that it is a crossed wire.

Though, it is the relay - flasher that transmits the continuous current to the hazards; that function could be gone.

Best,

PS: Yes, the connector was disintegrating and was effecting the low beam function. That is now fixed after the replacement

you have 2004 TJ? Get the factory manual pin-out diagram and double check every wire at the switch connector. Sounds like the 12v+ un-switched supply but may also be the leads to the hazard switch.

With a Jeep they probably swapped the order of a few wires just to be different each model year or package. 😉
By the way how much did the replacement connector cost? I'd like to get one bare with out the wires but so far I've only seen with them.

Issue solved!

There are 2 very similar wires going into the connector:

-Wire 11 (lower row far end towards passenger side) controls the Hazards and it is BLACK & WHITE
-Wire 3 (upper row, 3rd from the passenger side) is a fused Ignition On wire and it is BLACK & GREY

These wires were switched!

Now, with age, these 2 wires will become very similar in color. However, 11 is 18G and 3 is 20G. The thickness is obvious.

So, don't make the same mistake I made and mark any similar color wires the way you will recognize them.

Now, after the correction, the hazards are operational with ignition off as they should be!

FYI,
