Turn signal issue, stays on when unlocking with Fob

Can someone point me in the right direction? I’ve had my 08 taco for 6 years. I installed alpha Rex led headlights months ago. When I unlock the truck with the fob the blinkers flash like always. But, the drivers side rear stays on solid for 20 seconds or so then goes out. Driving the truck the signals all work fine. When I lock it with the fob the signals flash normally but don’t stay on. Only does this when I unlock with the Fob. Fuses are good, bulbs are good. Any tips? TIA

 

Do you have an aftermarket alarm or remote start installed? If so I'd start there, if not it sounds like a contact in the flasher relay may be getting stuck.

 

Factory alarm and no remote start. I’ll try the flasher relay. Would that just result in getting a new relay?

 

The Turn Signal Flasher controls each bulb individually so if there's nothing aftermarket tapped into the wiring I don't see what else it could be.






Not in a fun spot to get to though.

 

If it were just the relay, you'd get an indication on the dash also. I guesstimate it's flasher and BECU.

 

I’ll dig into it some more this weekend and try that. Thanks fellas
