With the hamster sounds and all you guys might check the filter, it comes out very easily from under the glovebox, I pulled mine for the first time in about 25k and it was all full of garden debris-looking stuff, some had managed to foul the fan a little and made some ticking sounds. No permanent damage and I just blew out the filter with compressed air and we were good to go again.
ps Hey Squat, did you get your wing down? ...I'm having a hard time not making an off-color remark about you flying at full mast all the time - but I'm afraid I'll get spanked again.
