srgilbert Posted July 16, 2006 Share Posted July 16, 2006 Hi, I have a 95 LS400 and with the hot weather I noticed that the LS takes a long time to cool the cabin - longer than I remember last year. Other than taking it into the shop $$ is there a sight glass on these that will help to tell if the freon is low? If so what is the procedure to use? Thanks - keep cool!
