Hi I'm stuck in a game

I have 3 main quest but when you set as active any of them they don't come up on map so I don't know where to go. Nothing has changed after installing 1.06 patch

Are you sure the quests don't relate to a different map? For example, if your main quest is in Skellige, and you are positioned in Novigrad, it will not show on the map.

Yes i'm sure it's not on different map

nice.... without quest markers people cant even do quests now =\ that sad.
well, I know this game do not bother explainig where you should go (designed from scratch to make you follow this pesky markers) - but about half of the quests are palyable without them. if you follow their story carefully.

about you problem - just watch where you should go on youtube videos / guides (beware spoilers) and pray for next quests to be unbugged

is it possible to reset last quest somehow?

I dont think the problem is in quest markers - maybe some npc disappeared. or quest is entirely broken.

no idea how to reset quests =\

Perhaps you should tell people which quests you are having trouble with, and exactly what stage of the quest you have selected, and what the text says.
