Hi guys, bought an 02 x5 a few weeks back and have been having problems with the aircon/heater fans making a noise. Its got worse since the day I got it.

Heres a link https://www.youtube.com/watch?v=3kHFKRuMuC8

I've been googling around and I'm thinking it might be the blower motor? hoping not as its a huge job so thought I'd ask for some advice first.. any help would be hugely appreciated! If theres any way I can test which of the 2 this may be would help.

Thanks in advance!
