Windscreen Demister Trouble

[BobbyBCFC]

New owner of 59 Fiesta. Windscreen Demister vent seems very very lack luster. You can certainly hear it roar on full power however, very little blow! I would say 60% of the windscreen is being cleared.

Imagine Goggles in a rectangle shape. That is the sort of clearance I am getting.

Any ideas? Air Filters?

Not best of starts; failed MOT too. Some donkey's (Ford Garage) at last full service, about 1000 miles ago thought full service meant oil change only. Brake pads are shot. Will change other wise immaculate car :)

Don't forget to use the air con. I saw a good few cars with steamed up windows on the motorway yesterday. I had my fan set to 1 with the aircon on and no steaming at all. If you are referring to cold mornings the air con deactivates below 4c I believe but use the heated windscreen if you have it to de mist the inside.

No AirCon. Style. Putting my hand onto the vent I feel barely anything on full (4)?

Really appreciate any help!

Is your windscreen dirty? Clean windscreens demist a lot quicker. Also have a look at the pollen filter, may be clogged up a bit

Marc thanks for the reply. Before reading this I took out the pollen filter this morning. It was the blackest filter you will ever seen. Now the air storms out! Success!! Thanks for the top diagnostic though!
