Hello, My father has a 2-door '85 Crown Vic. He's had this car since '95 when he got it with less than 30k miles (just rolled over 80k this weekend). As long as he's had it, the buzzer that reminds you to take your keys out of the ignition when you open the door, and presumably doubles as a headlight alarm, has never worked. I located the buzzer and tested it with a power supply, and it worked fine. The interior lights in the car work fine, so the door switches are ok, unless there is another one I can't see. Is there a common problem that might cause this? All of the fuses are good. My car is a '93 Escort, and most of the things pertaining to the door switches (interior lights, headlight alarm, automatic seatbelts, etc.) are handled by a black box under the driver's seat that contains a bank of relays and such. Is there a similar box in an '85 Crown Vic, and where might I find it? Thanks for your help. Dave
