Hello, I Am Looking For Help Diagnosing My Impala's Illness. About A Week Ago, my car overheated on the way home from a short trip. I Assumed it must be the thermostat stuck closed, so I Replaced it. Car Still Overheats. So I Replaced Water Pump. Car Still overheats, and Fan Does Not Come on, So I Replaced Fan. Fans Still do not come on, and horn does not work. I Took bottom horn off, (there are two) and tested it....BEEEEEP....Horn worked. Put Horn Back on, Took car to auto repair shop, and asked them to do an engine diagnostic check, which I thought meant they would hook it up to machine which would find short, etc. They used hand held scanner, and found no issues, but offered to fix my car for 495.00. Nice Guys. I brought car home, and checked it for short by pulling each individual fuse, using test light. No Bad Fuses Found. I am at a loss as to what the problem may be. with no horn, there is no beep when I lock my car, but lights flash letting me know its Locked. Also when I Hit Alarm button, lights flash but no horn. Please help me decipher this issue, as my car is upset I Haven't been driving it lately. ( And so is my boss lady.) There are no leaks (Visible), no dash indicator trouble lights, and I've never had any trouble with car prior to this. Any help would be appreciated.
