Turn signals and hazards intermittent (1 Viewer)

[ryukyudiver]

Over the last several weeks I've had a problem with my turn signals and hazards not working. One day they would work fine, and then mid cruising around, they would stop working for a couple days. Then the truck would sit for the weekend, and everything would be back to working as intended. Then a day or maybe even a week would pass and the hazards and turn signals would crap out again. I switch out the OEM turn signal relay with another denso relay, and the same problem persisted. Has anyone experienced anything like this before and found a solution? I need a good starting point.

I understand the issue comes up and stays for some time.
Once the issue is present, this gives you some time to check the entire contact chain end to end and see where it is interrupted.
You need a FSM with the wiring diagram.
With the issue present ...
I'd start wiggeling / replacing the fuse. Just to be sure it's fine...
Then at the relais: Check whether trigger power from the control switch as well as general power is there.
I bet one will be out. Then work your way towards the culprit.
Probably it's the control switch on the steering wheel..
Good Luck Ralf
