I recently got a 2000 xj, everything's been perfect aside from this little problem.
When I hit my brakes and turn signals together my 4 ways/hazards come on.
All lights work on there own and no other combination makes this problem.
The lights turn back off as soon as I turn my blinker off or let off the brake, whichever comes first.
I was thinking maybe my multiswitch?? But that shouldn't affect the brake should it?
I don't know where to start. Ideas? Any help would be greatly appreciated.
Any trailer wiring ? Any issues with the steering column wiring harness ? Multifunction switch failure is somewhat common.
Thanks for the fast response
I was also thinking the trailer wiring, But I took it out and still does it. Noticing it's not all the time though. 1 outta 5 tries or so. (with or without trailer wiring)
No issues I can see with column or harness, I traced it as well as I could and it seems pretty solid.
Also checked every fuse, light and electrical component, everything else is golden.
I would just assume it's the mf switch, because as you said, I read it's a common issue but I can't imagine the brake lights would run through it?
i dont have an xj but my wj is a 00 and the tail lights have a circuit board in them and the stock bulbs made it get too hot and it melted the plastic clips holding each circuit in place so they would move and touch and cause all kinds of wierd combinations not sure what the xj tail ligh is like but i thought maybe it might help if that is the problem when you get new tail lights run led bulbs they cause the circuits to not get as hot because they pull less power
Again thanks for the responses!
Ya, I'll have to double check bulbs. As CJ7-Tim said, not board on the xj, just an easy quick release section, which, as the rest of the wires, seems mint.
After checking the bulbs I guess I'll have to switch out the multi-function switch and see what happens
I'll post how it goes. thanks again
I don't see the relationship between brake and turn signals. They are separate bulbs. I'm thinking a bad chassis ground. To verify, wait until nightfall, turn off parking lamps and headlights. Then try your hazard/brake/turn signals. If the dash lights come on, you definitely have a chassis grounding issue.
