battery went dead. charged it up to use for a few days then replaced the bat. but after battery went dead and re charged, the fan would only work on slow speed and the ac snow flake wont come on. this is all i know of that is not working. i found a post on this prob. so i join your group to see what the fix was for this. the other post (that i cant find now) says he went to dealer and was told the car went into transport mode. (dont know what that meens) but dealer reset something now all works good, so he said.
