When the weather gets very cold here in St. Louis MO the lightss on our Vibe come on, running the battery down. The battery and generator have checked out. Our mechanic thinks it may be a problem in our add on alarm system. What can we do to solve this problem?
disconnect the alarm system and see if the problem goes away. If so, you know it is the problem, if not, take it to a good mechanic who specializes in electrical issues.
also, when you say “lights” do you mean the headlights, interior lights, ???
