I need a new condenser on mine, quite common according to the Ford Dealer. Not paying £400 to get it sorted though.
My parents had a similar issue, Vauxhall wanted around £400, dad bought one from the web and we installed it, fairly easy on the Vectra, only annoying thing was getting one of the threaded bolts out of the old condenser and had to make sure the shoulder was level with the bolt hole to get it to seal.
