I have a p reg disco which i've had about six months. With the weather getting colder I have discovered that the heating doesn't get warm on the drivers side - passenger side is fine but I'm having real probs clearing the windscreen on cold mornings, any ideas?

Hi folks Just bought my first Landy - '96 disco 300dti manual I've driven a few over the years and finally bought one yesterday I'll probably be asking LOTS of questions esp. when it comes to maintenance etc. Cheers
