Eg interior light problem.

Hi. i just changed flush my coolant. But now my temperature adjust section doesnt light up. Only the buttons light up.
When i twist the lights on 1st click they alternate in brightness between the cluster light and temperature/clock lighting.
Sometimes the temperature lights will go on but only the left half of it. And when i press the vent close/vent open the temp lights will go out again.
How can i fix this?

yea the lights were working before. not sure if it was coolant change that cause it or not. maybe just coincidence.coolant works fine.
It just annoys me when sometimes only half temp light turns on. i want all off or on. i kinda memorise what button do so dont really need light.
Just wanna know it will worsen other electronics in my car.
