Hey guys. As a new guy on this forum, i need some help.

I've lost my illumination/lighting in my analog cluster, just the 4 main ones. All the small indicators like handbrake warning etc. does work as well as the clock.

I fear that my dimmer switch is broken, because i have power to it, but nothing from it.. All fuses seems to be okay.
Has anyone looped the wires or something to keep them bright all the time?

PS: I have the 180sx model 1991, which has the button you press either up or down on the left side of the steering column, with 5 wires connected to it. I've read somewhere that you could just ground a red/yellow wire, but i have 2. As well as 1 black, 1 red/blue and 1 red/black wire(which is power in). I don't have a TCU unit installed either..
