passanger side leaking from boot area Whaat can i do to fix

 

If you mean that there is water inside the car on the passenger side, where the passengers feet go, then there are a few possibilities. If it has a sunroof, it might have a drain line for the sunroof area plugged or the drain line is disconnected. See this video . If it is not that it is probably either the AC evaporator drain has become plugged or has come out of its fitting in the floor, or the heater core is leaking. If it doesn't have any smell and you are sure it is just water, it is the AC drain is plugged. See this video If it smells like freon/anti-freeze then it is the heater core leaking and you either have to repair or replace the heater core or do without heat and re-route the coolant lines. If it is the heater core it is very difficult to fix because the whole dash has to be removed and it is a monster job. You can just re-route the coolant lines under the hood to bypass the heater core. There are lots of videos on how to do this on YouTube.
