Technical Heater fan started to make a vibration noise on setting 3 and 4

[hayfaye]

Only just noticeable on setting 3 but on 4 it's easily not just a fan noise.
Any ideas would be grateful before I have to take it apart

Possibly just rubbish in the fan area....underneath the glovebox is where the fan lives. Three bolts holding the fan in place but it;s a pain to get to and undo the bolts. I found some leaves in my one a while back..it could also be that the bearings on the fan are going but pretty sure that's rare I think.

Some heater fans have a small balancing weight attached to one or more of the blades. If any of them have fallen off, the fan could vibrate at certain speeds.

Hi , did you solve the problem?

So if anybody has the problem with the noise, the screws might be loose , so you need to tighten the 3 screws on the fan as i did. I changed the fan as well, it cost only 50€. The new fan is much stronger.
