I have a replacement in my spare parts in excellent/almost new condition that I can put in, but that will be an afternoon project....maybe next weekend I will look into it, if replacing my thermostat Wednesday doesn't help. It probably is the aux pump.... However, I have it fused at the plug (that red wire thing in the pics) and it hasn't blown the fuse So I have no clue....if it was dead you would think it'd blow the fuse. Its only a 1A quick-blow fuse.
