My LS has 73,000 miles and the Mark Levinson/Nav/Climate screen. It has just started having this issue this year (since using the A/C). The blower fan is fine, but sometimes I get nothing but hot air. Sometimes I get in the car and it works fine, even with several trips a day. This morning I got in and it wasn't cooling the whole way to work, which is about 10-15 miles. I'm pretty sure the freon level is fine because when it does work, it's cold. Anyone know what this could be?
I'm not sure if I should go to my local AC/cooling business, or to my Lexus dealer.
Sometimes I've had good luck with pressing "Auto" when I turn it on rather than pressing the fan speed buttons on the display.
