Condensation on the windscreen & windows

HI All,

Please can someone give me some help with this....

I have a golf MKIV 1.9 GT TDI on a 2001 plate which mists up whilst driving, especially motorway driving.

Now the climate control blows out both cold air and warm air when set. But when it rains the windscreen starts to get condensation on it and then eventually all the windows in the car. When I press the windscreen button on the climate control to clear the windscreen nothing happens.

I have run a scan using VAGcom and it has come up with the following fault code

01274 - Air Flow Flap Positioning Motor (V71) 37-00 - Faulty

I know alot of people are going to say its this that needs replacing located behind the glove box. Having read some forums they say there is usually an annoying sound which can be heard associated with this coming from behind the glovebox, but I can't hear anything??

Any help would be greatly appreciated.

Thanks

Rich

You might have the flap broken and therefore it's stuck in the fully recirc mode, stopping fresh air from outside getting in, and hence that's why your windows are steaming up.

You'll need to investigate the recirc flap to see if it's at least in the closed position and then 1st step just to manually push it to be open and see if they fixes the steaming up

As suggested, I would simply grab the flap and move it to the open position.

To do this remove the pollen filter and stick your hand in the hole, the flap is right there ! (that sounds filthy) :wub:

If the flap is in open position, unless it self closes at higher motorway speeds then as CT.p has suggested you could be at the early signs of a leaking heater matrix or the supplying hoses.

It'll only be small amounts to start with .
Apparently coolant leaves a sweet smell , and or oily residue to the glass .

Just an update, I went down to the Midlands this w/e a 2 hour drive on the motorway.

I didn't have the climate control on all the way their the windscreen was ok, it was a fine sunny day there and back.

However on the way back and just before I exited my junction I decided to put the climate control on. First on low and everything was ok, then I put it on high and the windscreen started to mist up slowly. I then put it back to low and also pressed the button for defrosting the windscreen and it slowly started to clear.

So any ideas, bearing in mind I still get the Airflow Flap Positioning Motor (V71) fault code??
