Radio backlight doesnt light up - B5 S4

[rubbndubbn]

I recently purchased a B5 S4 and one issue that it has is the backlight on the radio doesn't light up when I turn the headlights on. The climatronic and dash lights all work normal and the radio buttons light up if you push for a certain station just nothing else does.

The previous owner mentioned that he had been blowing a fuse in the car and took it in to be looked at and they said the cluster was causing the blown fuse. They then replaced the cluster and when that was done the backlighting on the radio stopped working. He said that he didn't want to keep paying for repairs due to the expense he had already paid for a new cluster etc. I called the shop to just get an idea of why the radio backlight not working would occur after the cluster install and they said that they didn't know but to bring it in and it would take about 1-2 hours ($210) of diagnostics to see and then they would go from there.

I attached a picture to get an idea of what I am talking about. Any help would be great... If I have to take it in then so be it but I would like to see if I can figure it out on my own time as its not a dire mechanical situation that needs to be attended too.

thanks in advance!

Since someone already mentioned in a different thread, its not just the radio as the ESP, fog lights and seat heater backlights don't work either but all functions do work.

Final bump in hopes to fix this!
