The climate control in my 2011 Sienna resets / turns off after I turn off the car. Whatever I had it set to--heat, AC, fans--after turning off the car for a while, the climate control simply turns off. The light for the defroster is amber, but no systems are running. It doesn't happen each time--only after the car has been sitting for a half an hour or more. After a few moments, I can tap in the settings I want. Not a huge deal, but annoying. Does anyone have any suggestions for righting this problem? Thanks!
