Hello Edgardo, you should have punctured the heater radiator and you will have to change it because it is plastic and normally it has no repair, the disarmament is somewhat complicated because you have to disassemble the console and part of the board, I advise you to take it to a house specialized in the subject and provisionally you can make a bipass joining both hoses with a tube of the right measure and 2 And do not download refrigerant in the room, luck and a 拥抱。
