Driver's Side Climate Control keeps setting at "LO"
I'm aware that this might be in a thread somewhere, and I also know it might not be specific to the 3rd Gen RX350. We have a 2010 RX350 FWD with Nav (which might have an impact). We are the sole owners, and it now has 198K miles on it. Today, out of the blue, the drivers side climate control temperature dropped to "LO" and it won't change. If I hold the "^" button down, the set point will go up, until I release the button, then it takes the temperature back to "LO". It seems like the dual zone works as it should (like really cold air coming out of the drivers side, and temperature-controlled air coming out of the passenger side). Any idea what it could be? Is there a specific fuse that controls this that might have blown? I checked the fuse listing in the manual, and there are about 6-8 that have "air conditioning" somewhere in the description. We have a terrible Lexus dealer closest to us--I really wouldn't trust them to change the oil at this point. Any thoughts out there?

I found an opposite problem on another website thread, and it was stuck in "HOT". Found that it was a stuck button. So I went and tapped the colder "v" button a number of times and that has, for the time being, caused the symptom to go away. I can set the temperature at whatever driver's side temperature I want again. Relief!!
