2016 Toyota Tacoma AC comes on during defrost



Peculiar problem I just noticed. When the interior fan is switched on, and the air is directed to the windshield defrost position(s), and the temp setting is at low (NOT max a/c), the a/c starts sending cold air out. A/C indicator light does not come on, though. What’s going on? Thanks!


Most cars automatically turn on the A/C when defrost is selected as the conditioned air helps the defrosting efforts by removing moisture from the air
