First I need to thank all of the people on the board for
keeping this forum active. I've already been able to solve
a number of problems with the archive and search.
Here's one that I haven't been able to find....
I have a 1995 540iA. I have an intermittent problem where
sometimes after starting the car I can hear the rather loud
and annoying drone of a fan from under the passenger side
dash. If I turn the climate controls completely off the
noise persists. I recently had the glove compartment out and
was able to track the noise to the set of heater vents in
the front of the passenger footwell.
So...Any ideas as to what this might be. It's an intermittent problem, only heard while the engine is running. I wouldn't mind it so much, but it is rather loud and sounds like this fan (or motor) may be on its way out. I've checked and can hear no strange sounds from the engine compartment.
