Help! Ford fiesta air circulation not working Car steaming up

Hi

I own a Ford fiesta 1.25 zetec 1999. Just recently i have started to have problems with the air circulation. The car is constantly steaming up! The only way i can clear it is by having the air conditioning on - which sees the power and fuel drop!

When i press the air re circulation button, nothing happens. There is no fresh air coming into the car. It sounds as though the switch is broken - it isnt though i have replaved the heater control panel and still nothing happens. Can any one help please ?

Thanks Richard

Forgetting air con for the moment. Does it still happen on cold heater setting? Could be a tiny crack in heater matrix letting out steam.

In my experience re-circulating the air in the car only aids in steaming up the car. Without air-con using a not-too-hot and definitely not absolute cold setting should clear it.

You may have a leak, passenger footwell or rear-windscreen perhaps? It really shouldn't steam up madly every time without fail unless water's getting in.

Don't use the re-circulate use the fresh air option. I find leaving the window open fraction helps while the blower is on, just gives the moist warm air an easy exit.

Lick the window...(no seriously)... Does it taste sweet/leave a greasy oily smear that is a beggar to clean off? If so you possibly have a leaky heater matrix and the moisture is coolant... Check the levels!

Lick the window ! Lol probably best not to try that while you're driving, apart from the funny looks you'd get it'd probably be a bit dangerous!

Maybe running a finger through the moisture on the screen then tasting the tip of your finger would be a better/easier option!

But you're right about what you say about leaking heater matrix.

Also using "recirculate" is a bad idea, especially if you've been using the aircon. Recirculate simply blows the moist air in the car (and any moisture that has collected on the heat exchanger if you've been using the aircon) onto the windscreen making it steam up, better to put it onto the fresh air setting. Or if that doesnt work you'll just have to switch off the blower and open the windows, and get the leak or faulty recirculate/fresh air knob fixed.
