1997 Kenworth t800 flasher problem need help

Hey I have a 97 t800 dump truck. The rear blinkers keep blinking and will not stop got a mechanic to check all wires found nothing. Have anyone ever experienced this problem and what resolved the issue?

 

Just rear turn signals, not front as well? Both sides or just one?

 

It’s just rear not front I just notice when I press the brake it stops the ticking noise

 

One side or both sides?

 

Both

 

Might be speaking out of my but on them older trucks with that signalstat contraption for turn signals sometimes goes funky.

 

No, that’s where I’d start too. Because it controls indicators and 4-way in the one unit.

 

The front not doing it too kind of puzzles me though. I'd need to see a schematic to see if they're on the same circuit or not.

 

I just remember the nightmares from them things, just in the right place for that coffee to splash on with a huge bump, but it can be my dementia
