Dash lights flicker when signals are on

[Strict_Lychee1780]

I have a 2020 Hino 268 and noticed the dash lights flicker when I use the turn signals. It doesn't happen all the time, but it's starting to annoy me. I checked the fuses and bulbs, and they look fine. I thought maybe it was a loose ground, but everything looks okay. I think.

Has anyone had this problem before? Could a bad relay be the cause? I'd really appreciate any advice.

It's deinfetly an electrical issue and you're on the right track with the relay or the loose ground. On the ground side of things the problem could also be corrosion related. While it's not too common, I would still check the wiring to make sure it's all good.

That flicker could definitely be a sign of a weak ground or a failing relay, had a similar issue on my 268 and it turned out to be corrosion on a ground point behind the dash. Cleaning it up fixed the flicker instantly.
