Hi everyone,

My 9-5 has started producing some kind of intermittent high pitch whine
(without any cheese :) which is audible from inside the car.

The weather here has been pretty cold these last few days, so at first I
thought perhaps it was a semi-frozen belt of some kind, but the sound
appears even after the engine has warmed up thoroughly.

I then thought it might have something to do with the power steering, as it
seemed the sound was produced when I turned the wheel, but that theory, too,
was proven wrong yesterday as the pitch was back as I was driving straight
ahead. The sound will also make itself known even if the car is standing
still with the engine runnning, fan off, radio off.

Any thoughts?

Kind regards,

E

I also get an intermittent whine in my C900T. It comes from the
passenger when I go through the turns on the back country roads :-)

I have noticed a similar sound, it is coming from the blower when it is set
to the upper vents (not set at floor). It does it when the blower motor is
on high, if I readjust the blower to floors the sound goes away.
