I have a 2014 LS460L AWD which I bought new. Since ownership, climate control would start when car was started but a few days ago it no longer does. Is there a switch I hit by accident or is this something a mechanic needs to fix?

 

Have you checked the "auto" switch on your hvac controls?

 

Check the cabin air filter, If not in right that will cause it to do that

 

I'm having the same problem with my 2007 LS460L. When you start the engine your AC is no longer on. When you hit the auto button it turns on at 75 every time.
there is also no heat and no air coming through the vents. I'm thinking its the blending door actuator. I have been researching and coming up with no help.

 

yes it is in auto position

 

Makes sense I just had them changed when oil change was done. Are their 2 cabin air filters one on left and another opposite side of engine bay?

 

Cabin filter is in the glove box, Only one Your thinking of the engine air filters yes two on each side
