Doors Dont Turn On Lights

[MHG]

So my 2025 has both the map light and the bed lights switches set to door. But the lights wont turn on when any door is open. However the dash indicates the door is open and the lights function if i set the switches to on. So its not a door switch or a fuse.

Am i missing some setting?

Are your lights set to "Door" on the center top controller?

Yes it is. So is the one for the truck bed.

So Toyota had the truck for half a day and could not fix it. Like most dealerships they waste time going down your aftermarket wiring rabbit hole as it a connection to B+ , B- and IGN is going to destroy the cars electrical system.

Seems i need to make another appointment to leave the truck there. Well I guess I’ll need to uninstall the three aftermarket wires so the tech can stay focused.

That is a good idea. Dealers jump on any excuse to avoid taking care of our trucks, so why give them ammunition?

Do the lights all turn on if you move the switch to the "ON" position?

Did your lights ever turn on with the doors opening?

What exactly have you done for DIY wiring? What wiring on the truck did you touch?
