ST170 Instrument Cluster Background light
 

So, my instruement cluster and oil gauges to the side arent lighthing up. The green background light does not come on. What can be broken? I heard some transformator on oil gauge panel is the problem but i need the exact location of it if someone replaced that with aftermarket one. Thanks in advance!

You might need a new set of gauges cause I'm sure these isn't a bulb in the gauges.
