Ok, I ended up with a 40th Anniv with the much maligned climate control system. So, I then sat down with the trusty owner's manual and expected to read about how it works... Nothing. Just some vague info about the non-auto climate control. I did the usual search here, but found nothing particularly helpful in figuring out how this thing works (or doesn't). I'm assuming the LX450 manual would cover this. Anybody know for sure, or know the ins and outs of this thing. Basic question is "what does the yellow light on the Auto button mean?" And on a related note - it looks like one of the bulbs behind the climate system is out. How big a deal is this to take apart? I appreciate any help, DocMallory _____________________________________ '97 locked 40th Anniversary Still has that "used car scent"
