Let's start with what you have, first, please. Read this post and then return with more info.My car horn just goes if one short beep right after starting car. It'll also do this after driving sometimes once I put it in park before I turn it off. Any help would be appreciated. I don't have any door buttons sticking. Also there's only a keyless entry system not an alarm on it.
It may also be of note that the last post in this thread was just over 9 years earlier than yours, so it's not likely any of these folks will be responding.
