Anthony Hughes Posted December 17, 2007 Share Posted December 17, 2007 I have a 2006 LS 430. Is it necessary to turn the A/C switch off when operating the heater in Auto? Or does it make any difference? Quote Link to comment Share on other sites More sharing options...
sonyman Posted December 18, 2007 Share Posted December 18, 2007 It's not necessary and I would recommend leaving it on. Contrary to what many think, then A/C system does more than just cool the air; it conditions it, with respect to humidity as well. It's also good for the system to run year-round for longevity, which also goes against conventional thought. Quote Link to comment Share on other sites More sharing options...
