Hellz I believe you are correct that it is a ac issue. The other day I turned on my ac and it started making that noise....turned ac off...noise stopped. Any idea why it is doing that, or what needs to be replaced? Also, can I just disconnect or pull a fuse to the ac altogether? I live in wisconsin right on the lake so we usually only have 1 day a year that you would need to use the ac anyway!
Thanks to all that have offered their ideas so far
