PLEASE DON'T SHOUT. You had me with the title.
I reckon that if someone were to give you detailed instructions, it would look like a manual, so I do recommend looking through this web site for plenty of links to manuals, not all of which are in Russian.
That said, here's what I can suggest, but I wouldn't recognise your car even if it were to run me over. So. Post some pictures of the fixed cables, and of the hole where the dashboard was. You cannot really be sure that you acquaintance fixed them properly.
I expect that you try replacing the cables first. Look for disconnected sockets.
If there's anyone here who knows better, please join in.
