LuvmyLexus Posted August 12, 2015 Share Posted August 12, 2015 Hi: I have an 07 LS460 and the AC system has a hard time keeping the cabin cool. I Live in texas so it's hot but the AC fan/blower never comes off of high and the cabin is still not very cool. I have put a gage on the Low side port and it appears to be full. Any suggestions? PS I also have a 2002 and a 2004 Ls430 and their AC systems are great. In fact the 2002 will freeze you out of the car. Thanks Quote Link to comment Share on other sites More sharing options...
sadclown Posted August 13, 2015 Share Posted August 13, 2015 Either there is a coolant leak or your radiator and evaporator needs cleaning. Quote Link to comment Share on other sites More sharing options...
