Sorry, my bad (was going on info from the wife). I tested this out last
night - it only happens when the defrost is on, so according to John Sevey
and Lon Stowell, this is normal. Good to know, thanks guys.

Cool!

Or should I say, "Less humid". :)

By the way, your 2000 probably has two "defrost" positions on the HVAC
selector ****: defrost, and defrost floor.

That means that the A/C compressor will/should operate on: a/c, max a/c,
defrost, and defrost/floor. That leaves (I'm recalling from memory here) off,
vent, and heat/floor as the _only_ positions where the compressor won't
operate.

You probably already found this out, but I thought that I'd clarify -- since my
original post wasn't all that clear...

Thanks, I was starting to think that I might have a problem on my hands.
From what I can tell it's only happening when it's on defrost or when
the AC is on.
