Like Roastbeef says blower under/behind the glove box. May be coincidence - been washing my engine with water for years with gentle spray - but I did have a noisy blower that made me take it out and lubricate, which was easy. Suggest you take a look, maybe take it out or check cabling to start with. Water can certainly come in that way which is a reason to rosty cables incl BMW call back on this very harness.
