when the fan is on at low speeds, it starts whistling. I think I either have a bad motor or there's something stuck in there.

Any suggestions on what to take apart to look?

Mine whistles when you first turn on the front defroster. It starts blowing like crazy and whistles some before the top vents fully opens. Which vent are you using when this happens (or auto?)?

Take it to the dealer. I had the EXACT same problem and they said it was the "Final stage resistor" or something like that. I have the work order but not on me right now. Lemme know if you need it. BTW this is definately not something you should try fixing yourself. My dealer had fixed this numerous times before on other e46's, talk to you dealer, they should do it for free. After i got my car back it hasn't happened since, works good as new now.

Think they'll do it for free if I'm past my warranty?

Do you know of a service alert or anything?
