Lada Car Door Won't Shut

It's the Lada's turn today as the feezing cold morning usually congures something up to go wrong in that department. As I got back fromt he factory drop and tried to close the Lada door, it just bounced back open! Looking closer, the spring inside the latch has broken. So now not only have I a Lada door that doesn't close, but it doesn't lock either as that bit of bad luck happened month ago!
