the sole function of the solar sensor is to info the climate control that there is a sunny day ---> that means that the solar rays warm up the skin and the uper body will feel somewhat hotter that the rest of the body ---> therefore the [earlier mentioned] "air bypass damper" will open up and the air blowing from the upper vents will be a little bit colder than the set temp. all of that happens only in auto function mode! if you manualy set the temp and blower, the solar sensor feedback is DISREGARDED.

the solar sensor provides the a/c amp module with the output voltage of 0.8 to 4.8 Volts depending on how sunny it is. anything below 0.8 volt is considered by a/c amp module as dark/no sun condition.

my earlier post is pretty much self explanatory. If anybody still thinks they have two solar sensors in their tundra, I'd be happy to take it off your hands (free), once you realize you need only one

BTW I hate to go off topic, but anybody cares to explain the "day/night mode"? also, does ltd tundra have auto headlights? does that mean they adjust the hight automaticaly or they turn on automaticaly? thanks
