HVAC whine

Just looking for a little help/pointers here I think, I have my second service appointment set for tomorrow morning..

My WK2 seems to have developed the HVAC/AC whine that was mentioned in a few posts and this TSB (http://www.wk2jeeps.com/tsb/tsb_wk2_2400711.pdf). The TSB mentions that it applies to the AC on at fan speeds 1-3 on vehicles built prior to March of '11. Now my vehicle was built in June '11 and with weather getting a little colder up here in MI I've found that this whine occurs whether the AC is on or off, regardless of fan setting (defrost, feet, etc), but still only occurs at speeds 1-3.

I had taken my truck in to Parkway Chrysler about a month ago for just the AC issue prior to knowing about the TSB, they could not replicate the problem. Naturally as soon as I pulled off the lot the sound started up again. Just wondering if anyone else had had this problem that extended beyond the scope of the TSB and how you might have went about getting it resolved. Id hate to get a call tomorrow saying nothing was wrong again. Its really getting on my nerves since the whine comes into the cabin over the radio even at freeway speeds!
