2005 Mercury Grand Marquis audible alarm keeps sounding but no visual notifications
Audible alarm keeps beeping as if there is a problem but there is no visual indication of any problem with the car; only the audible alarm from the car.
Could be a malfunctioning door switch, the unfortunate thing about this is it takes a tech that really knows his stuff with these systems cause it is really easy to miss the problem as there is so much information feeding into the security system that it needs to be checked more than just once through. very time consuming and so it is expensive to get it working correctly.
