Noise in central column.

Hi everyone!
It's one of those crackling/vibrating sounds when driving a certain speed. It's located inside the column right between the driver and passenger.
It stops when I push the column with a finger but it's kind of annoying keeping my finger there all the time ;-)
Does anyone have a video or pictures of what I will find there after unscrewing those 4 screws inside that compartment? I just don't want to go blind and end up unable to put it back together.

 

If someone would have the same problem:
There are 5 screws there. 4 are under the matt inside the container and the 5th is right above the cup holder behind a plastic cover. The plastic cover is on clips so just pry it with a screwdriver on one of the sides and it comes out. All screws are 10mm.
The thing that was crackling were lose washers. Those washers are on a hand/foot break line so when you don't use it the line is loosen and the washers can make noise. This whole plastic box resonates I guess that's why it makes it louder.
I just took isolation tape and taped those washers together. The hand/foot break works with no problems and the noise is gone.
Cheers!
