My Airxcel 13500 ultra low profile AC in my Hummingbird only has lo and high fan settings. I've determined that allowing the blower fan to run while the AC compressor is cycled off is causing a drastic rise in humidity accompanied by mold growth at the supply vents. I'd like to possibly mod my AC to include something like an Auto/On toggle that will interrupt power to the blower motor if the AC compressor is not cycled on. Does anyone know of a way to accomplish this? As always, thanks in advance for any info you guys can provide.
