I have a 97 Buick Lesabre with an electrical problem. The speedometer worked on and off for about a year and now it has stopped working . The tach is now working part of the time and stops working almost every trip. Also, after being hit in the rear the chime dings after the door lock button on the door is pressed like the key may be in the ignition but it is not, then I have to press the button again to lock the doors. Thanks for your help. I have read that it may be the speed sensor. Please tell me where it is located on this car.   Thanks,   LRJ
