      I have recently acquired a 05 P71 crown vic. In my mad dash to try as best I can to not make it look like a police car I have replaced the bumper covers removed a bunch of crap, changed oil, trans filter and other basic service. Car runs great, but have noticed at 75 mph the dinging begins. I believe it is some sort of warning? It also seems to happen at 80-85. How can I make this stop short of disconnecting the dinger? Any help would be appreciated. Thanks

        Are you wearing your seatbelt when this happens?

          I did a quick search and found this:

          “the speed chime is a standalone module located above the glove box. you can unplug the electrical connector from it without any ill effects.”

          Hopefully that info applies to your model year, this is the link to their discussion: Crown Vic Discussion

            OK just some quick details, seat belt does work as far as when it is not connected the light is on and will get the ding ding. The air bags seem to function ok, passenger in the car and lights up “air bag on” when no passenger is in the car it’s off. No lights are on the dash so all seems healthy and normal. It only occurs when the dash cluster hits 75. GPS says 73 so I believe Nodak81 is correct. It must be some function but not sure to which. I will connect a scanner to see what the PCM is displaying for speed but assume it will match the cluster. My seat belt is on and the speed limit is 75 so it’s quite annoying if you drop under it stops or if you go over it stops but as soon as you get to 75 ding ding. Doesn’t matter if your going 80 and slow down or if 70 and speed up. 75 is the magic number. Thanks Nodak81, I did a search and couldn’t find anything, just a bunch of speed times 0-75 stuff like that. Hopefully will have some time this weekend or if it pisses me off to much on my commute tomorrow. Again thanks to all of you out there and happy thanksgiving

              That’s so odd that a police interceptor would have a speed warning chime active in it. What’s the chance you could make contact with the department that used to own the car? Maybe whoever serviced that car could tell you why it’s been enabled.

                A little background on the car. It wasn’t a cruiser. Either a detectives car or some sort of community service car. Found paper work in the car with a detective name on it. So I’m going with a detective. There was never a cage put in and the normal back seat was never removed. The interior is mint so am quite positive it was never a regular cruiser. There was an issue with the auction and I ended up filing a complaint with the city for bait and switch. The car listed was not the car being auctioned. A few issues were reported and am fighting with the city’s fleet dept. would rather not call about that. I will see if I can find the connector and disconnect. Will report back as soon as I can

                  Hope everybody had a happy and safe thanksgiving. I’ve had no luck with finding the connector, thought it would be easy since there is no glove box. It has the door but when opened you see all the guts. Found 4 connectors, three for airbag, at least one the other two doesn’t seem to do anything when I unplug them from some kind of box. I assume it’s an airbag module. And the fourth is for the AC. Either which way when they are unplugged the dinging continues. Seems like I got a car that shouldn’t exist. Lol my luck. If anyone has any further ideas I would appreciate it big time. Don’t want to cut the dinger, I need it so I don’t forget my lights or keys. I’m often rushing around and hate to admit it but that thing has saved me more than once. Thanks again
