volosong Posted May 19, 2014 Share Posted May 19, 2014 A search didn't show a thread about my problem. This past Saturday, I descended a nine-mile road on my bicycle in 55-60 degree temperature. No suprise that I was quite chilled afterward and after loading up the bike onto my 2006 RX400H, I headed home and cranked the heat to "MAX HOT". Good! Nice and toasty to warm me up. So much so that after a few minutes, I reduced the temperature "one click", and the heat went way, way down. Not incremental as it used to do. Then I remembered earlier in the day that the "MAX COOL" really wasn't all that cold. It was only in the low 90s outside, and the A/C usually blows real cold. It didn't that morning. Any idea what is wrong with my A/C-Heat system? All else seem normal. Quote Link to comment Share on other sites More sharing options...
RX400h Posted May 19, 2014 Share Posted May 19, 2014 Maseace provided this info, a while back. It may provide a clue. http://uslexusownersclub.com/forums/topic/76194-rx-400h-air-conditioning-problem/ Quote Link to comment Share on other sites More sharing options...
