Does anyone know why when I get in my 09, ls460 when the car is cold the memory seats and mirrors etc. work fine, but the heat auto switch is on for 1 min and turns off. I have to select the heater to come on again every time the car is cold. In the summer the AC came on and stayed on and was auto adjusted to the setting I have programmed. When I get in the car temp and the temp is 40degress as example outside the car will not show the auto temp on the heater and won't come on. After a minute the auto switch will go out and I have to select auto and then the auto temp shows every time the temp I had saved in memory. If I turn the car off and get back in it while the car is still warmed up it works fine.??? what's up.

 

They fixed my car it was the servo motor on a vent duct. 2009 ls460
