I have an intermittent "whistle" that comes from the center console vent area of my 2005 LR3 SE7. It occurs when the A/C or heat is on.
I can sometimes completely eliminate the symptom by changing fan speed. ["Off" completely eliminates it, and very high or very low sometimes does as well.] The whistle seems dependent on engine speed as well, but the connection is not so clear.
The whistle is not loud, just a really annoying frequency.
The problem is that the whistle is intermittent and the LR dealership can't hear it (they couldn't in August and they couldn't today).
Should I just have the fan replaced or the duct cleaned out? Any thoughts?
