Front right turn signal stays on

Hello folks, I'm new to the group. I'm posting to hopefully get some help with an issue. I have a 3rd Gen 2018 Tacoma. Just a few days ago the front right turn signal started blinking on it's own without engaging the turn signal lever. After a day or two the light now stays lit solid. The rest of the lights are fine and work when actuated. Diagnosis is that side is getting a constant 12 volt signal, everything points to a bad relay however i'm having trouble locating said relay that could be bad. Toyota here in AZ wants 100 bucks just to look at it cause the 3 year warranty is up. Can anyone help me out? Much appreciated.

 

The front turn signals appear to be controlled directly by the Combination Meter (Instrument Cluster), aside from that wire being shorted to power somewhere only the cluster can turn it on.

 

Ok, doesn't look like something easy that I could manage. Off to the dealer service. Glad I paid for the extended warranty. Thanks for the response
