Rear defrost making noise??

[ja3118]

Hey all, 2019 Ram Big Horn. It finally got cold enough to use remote start this season and I noticed when I get in, there is a noise coming from the back seat.. Got it diagnosed to the rear defroster. Noise disappears when you turn that off. The sound is almost like a clicking/chattering sound, and is localized to the area just left and low of the center slider. I haven't dug into it enough to determine if the defroster is still functioning properly or not but am too nervous to leave it on for too long. I heard a rumor that I might have moisture in the window seal that is shorting some wires? Anyone have this happen or have better info? P.S. I'm past warranty, go figure.

Only thing that comes to mind is arcing from a poor electrical connection.
