So when you put the car in auxiliary mode ( power to the car but no on ) you can see your dash lights. All of mine work but recently the add coolant one went out and hasn't come back , I say this because that light would go out but would turn on when i cranked it and would show when the car actually had low coolant. What now ? How do i fix it !

 

The bulb could have burned out?

 

Don't you have to remove the whole dash ?

 

I think you can remove just the cluster, not the whole dash, but I have not had to do it yet myself. There is a process in the FSM to check the sensor and light up the dash, if it’s not burned out or a short in the circuit
