I have a 3G 6MT Base TL and I just noticed a peculiar noise this morning. This noise may be normal, but I wanted to post on here to be sure. I drove to work this morning (about 5-7 miles hwy) and got out of my car, only to hear this sound, similar to rattle (hard to describe), but constant while my compressor kicks on. The noise ONLY persists as long as my compressor/fan (maybe blower?) is on (which cuts on and off frequently, here in this climate). Its very humid here and it has just rained quite a bit over the past 3 days'ish, so this could entail something, not sure. If I turn the AC off, the noise stops, if I turn it on, you hear it in 5-10sec intervals. The noise is loud (noticable, but only really distinguishable when about 2-3ft from the car). I keep my AC on about 65 all the time (yes, I know, cold!) Any thoughts appreciated!
