All of the buttons on the driver's door a going crazy, as in the memory set, 1, 2, and the power lock button. When I hit 1 or 2 it doesn't go to the preset but instead my seat/steering wheel/radio/etc. do something completley different. When I hit the power lock button, it moves the seats and steering wheel instead of locking/unlocking the door locks. Also, I've noticed that you've been through the N* head gasket failure. Could you describe to me the symptoms of your car right before it happened?
