I have power mirrors, and I was TOLD there are power folding mirrors but I don't have the button in the middle of the mirror adjustment buttons to fold them in. The other day though, I SWEAR I saw my mirrors fold out(I didn't realize they were in) on their own. Is there some setting or option to allow for the mirrors to fold in/out on their own when the truck is parked and locked or something else? Or am I simply crazy?
