Heat works fine, on Sub Zero days, I find it helps to hit the Recirculate Button but that just so I can turn the blower speed down...
As far as the top noise, I found that putting a thin layer of silicone grease on the alignment pin and contact point the noise had gone away 100%... I was getting the noise over the drivers left shoulder at the b-pillar, where the alignment pin is, I also found that if I undid that latch the noise would stop, leading me to believe it was not because the top was loose, then I found a thread on one of the forums suggesting " NAPA Sil Glide ", happened to have it in the garage, that I used on my Jeeps to stop leaks on the hardtop, and ..... Problem solved lightly coated the pin and contact points with it wiped excess off with a rag so far no more clicking squeeking noise
