As the title says, yesterday morning my climate control in my r33 series 2 makes a *knock knock knock* noise when ever i turn the car on or change the mode the climate control is running in, i.e windows, to drives legs.
It sounds to me like plastic gears or something is clicking.
When i turn the climte control unit off an on again it usualy goes away, sometimes it clicks for 5 seconds, other times 20 seconds.
Is this a common problem?
Cheers
