I was loking at my mirrors and they are identical to the grand touring outside,I looked inside the grand and did not see a switch,well the should come on with the rear defrost,I joked with the mech. at my dealer and mentioned they look identical and its prob just a jumper to get them working,she smiled and said maybe but I cannot tell you that.Anyone know if there is a relay or a fuse(other than the 7.5 in left side kick panel)that can be added to make them work?
