Astra G - 16V - 98
few weeks ago i started my car and noticed that :
The airflow from vent. system is pulsating and i heard a knocking sound behind the glove box
On same time when you lay hand over vents you can feel how the flow is changing like you changing the fan speed knob from 1 to 2 and 2 to 1 and repeats ....
I hope you can get what i talk about
Any way i removed the glove box , and i sow that i have problem with the flap/vent that switch the inner / outer air ventilation.
I removed the motor of the flap/vent and the problem was gone ofcourse but i have problems with evaporation in the cope.
I tested the motor moving the flap when you press the button on the dashboard and i notice that :
IT DOES`T STOP TO ROLL AT ALL
If i press the air button it change the direction of the rotation but does not stop.
Can any one tell me what to do ?
- i drive my car like this and its annoying .......
