I recently bought an N reg Laguna 2L RT. And the heater only blows out cold air. Does anyone know what this is likely to be, and if so, is it worth paying the money to have it fixed?.
Sounds like the heater matrix is blocked, try running water back and forth through matrix from beneath the bonnet, if this dont work a new one will set you back around 60 quid, dont buy a 2nd hand one its probably blocked too.
