As the title suggests, my turn signals and hazards are not working. All fuses are good; I have changed the flasher module above the brake pedal and the turn signal switch in the steering column. I'm at a loss and can use a hand.
It's a 1998 Limited XJ 4.0L and is a complete build. Might be worth knowing that all of my lights are LED's. I have resistors on the rear turn signals and the fronts have built in canibus.

Thanks!

 

I know this topic has been covered and I have searched but my problem still persists so I figured I'd start my own thread

 

Did this happen right after the LED install?

 

Nope, they were working perfectly for a couple months. I did have an alarm put in a week ago though.

 

Now that makes we wonder. It's the little things like that we need to know.
Now whether this is the problem or not is another thing.
No experience with alarms in XJ's.
But you did say put in. So professionally?
Until somebody smarter then me chimes in if it were me I would go back and talk to them.
Cause aren't alarms hooked to lights?

I do have another question to but unrelated to your problem.
At least I am guessing it is.
Why the resistors on the rear lights?
And the canibus thing you mention is that for the headlights?
Cause I used LED's for all my exterior lights. Did not do LED headlights though.
I had no reason to use anything but an LED flasher.
With the exception of having a problem with the 194's in the side markers.
Can read about my experience here:

Do you have a test light? It's really hard to troubleshoot without a test light. Make sure you have power at the fuses would be the first thing I would check.
Why do you have fuses and a canbus? Canbus is supposed to provide over current detection and protection. If canbus isn't happy, nobody is happy.

The fact that you do not have flashers or turn signals makes me think you may not have power because the hazards work on the brake circuit and the turn signals are fed from a separate fuse. Could a be a ground or lack of a ground issue too.

 

The alarm was installed professionally and it's a barebones alarm so the flashers were not hooked up to it.
I have resistors in the rear turn signals to prevent them from hyper flashing. In the front I bought LED bulbs that have that feature built into them.

Hope this helps!?!?

 

When you say all fuses are good, have you checked in both the interior fuse board and the PDC under the hood?

 

Yep!

 

I just bought a new fancy DMM and it's quite different from the norm. Once I read the instructions I'll put it to use.

 

Now the problem with looking at the 98 wiring diagram is Cruiser54's website doesn't link one so I don't have one.

From the 2001 & 1995 diagrams, they work in the same way, just fuse numbers and wiring colours change.

Here's what you should find at the pins for the relay.

 

Okay so I am fresh off of having surgery and want to pick this back up since my turn signals are not fixed yet. I was wondering if somebody could give me a diagram of where the ground wire would be for the Flasher module and some direction in using a digital multimeter to solve this!!
Please and thank you!!

 

Its essential that you download the FSM and expand and study the Circuit Diagram

Boxburn posted an excerpt that gives you helpful info

Using the Ohmeter function set to lowest resistance, check the resistance between earth terminals and vehicle earth, which should be very low

imo, a test light is best tool for searching for 12V in this case

check every fuse ! (probe both ends with test light)

the positions of the fuses in my vehicles do not match their FSM or drivers handbook!
