This is a how to for people that suffer with GTVs that dont demist due to a faulty recirculation flap.
To diagnose whether your recird flap is faulty in a ph. 1 GTV, press the recirc button with the igniton only on. If you dont hear a motor turning by the passenger footwell, there is a good chance that your motor is broken.
To get the recirc flap out of recirc you will need to do the following:-
Remove the three 5mm allen key bolts on the bottom of the glovebox.
Remove the five(?) small allen key bolts inside the glovebox.
This will allow the glovebox to drop down away from the dashboard. Undo the glovebox light connector and you can remove the glovebox fully.
If you look into the hole where the glovebox was, you will see a flat piece of foam above the fan motor. This is the recirc flap. If it is angled towards the front of the car, it is in recirc. To get it out of recirc youll need to get the flap pulled towards you.
In order to do this, youll need to disconnect the motor. First undo the electrical connector which feeds the recirc flap motor. This is located to the left of the recirc flap. Its a small black connector.
Then, connected to the motor, you will see a small metal rod which comes from the recird flap motor and joins to the flap itself. This is on the left of the flap. There is a small plastic Alfa rod connector on the end of the rod. All you need to do is unhook the plastic clip from the rod and pull out the rod.
This will leave the flap "flapping"(!) about in its chamber. All I did was used some silver lagging tape, although any other super sticky tape will do, and I taped the flap so it is pulled away from the front of the car.
Obvoiusly you wont be able to use the recirc mode, but its a hell of a lot easier than replacing the motor, and cheaper!
Then all you need to do is replace the glovebox. Dont forget to plug the light connector back in!
Hope this helps demist everyones screens this winter!!
