My wife's 97 4runner has a new(?) issue. When parked the horn honks three times on it's own. Usually in the middle of the night. I'm getting a bit sick of running out on the porch in my boxers to see if someone is stealing the car. We're not sure if the alarm system is standard or aftermarket but it seems to work as it should other than this little personality quirk. Any ideas or similar experiences/fix ideas. I'm sure my neighbors love it. (IMG:style_emoticons/default/liebe011.gif)
