Yes, I have it too. In my case it chirps like a cicade (sp?) and only
happens when it's cold outside. Amasing thing: It becomes quiter when I
accelerate and louder when I brake. My speculation is that the grease in
the shaft/bronze bearing of the rotor of the fan's motor has dried out
and the rotor has a radial play in the bearings. Can it be lubricated
without having to go through the nightmare of the heater box removal?
Thx.
