Chirping sounds from dashboard

External Since: Jun 27, 2008 Posts: 3

I have a 2002 325i that just developed a chirping sound that is random and
seems to be coming out of the driver-side air vent. It sounds like a canary
warbling. Originally I thought it was caused by the air conditioning system,
but it also continues with the air system off. Could it be connected with an
air flow fan that is always on even if the system is off? Any suggestions?
Thanks.

There's a very small fan which runs constantly to circulate air over the
cabin temperature sensor. You can see it through the small grill next to
the controls. Perhaps something is touching it - or the bearings gone dry.
Try putting a vacuum cleaner over the grill to shift any foreign bodies.
