Need help with cluster

[240sxcnj]

My cluster lumination and the a/c controls lumination just stopped working the other day, I checked the fuses and they r all good. Help me please. Relays are fine. The light on the time works and the green lights on the ac/heater buttons go on but nothing for backlight, i have no issues with the wipers or blowers or anything of that sort. i work at nissan and my boss said it might be a ground but they all seem fine. They all stopped working when i put in a flip out touch screen head unit and then took it out and put in the old one and everythings still messed up. please help it sucks driving at night haha
:wtf:

I had the same problem. If you remove the black panel that covers the fuses on the drivers side you should see a white box connected to a harness. I believe its called the ecm module. Go to a junkyard and swap it out. You most likely shorted out that box when installing your radio. It controls a majority of the dash lights lol hope that's the problem

is there anyway to fix it without getting a new module?
