Hmmm... I was *going* to reply that the rumors I have heard are that the
old fans chew up resistors and the new ones are better.  My fan has been
chirping for years now in the winter and the resistor was bad when I got
the car.  I am *not* looking forward to replacing the stupid fan, so I'm
trying to make it until I need a heater core, too...

At least the resistors are cheap (or *should* be - they are an old VW
part, under $20 for mine)

Maybe you got one of the "old" fans, I have no idea how to tell the

I'd just replace the resistor pack and cross my fingers for now, if I
were you.
