1996 Buick Park Avenue Automatic
My Grandparents who are in their 90's have a 96 Buick Park Avenue. The problem is that they have replaced the battery twice and it still won't start most of the time. They have to keep a battery handy in case of an emergency. Also, recently, when they were out in the car, the horn just started blowing and wouldn't go off! And then a few days ago, the chime that goes off when your door is open came on and stayed on the whole time they were driving. They have taken it to the Chevy dealer who sold them another battery and told them they couldn't find the problem. And just this week they took it to garage specializing in electrical repairs and they said they can't find anything wrong, and also said that the battery has a dead cell. Does anyone have an idea how to help. They need a car that is reliable. They are thinking about getting another car, but they are 90 years old. If it can be fixed that would be great? Anybody have a clue?
If your willing to experiment? Go to fuse panel left side locate fuse 9C 10Amp pull will kill chime but also radio. Next go under right side find relay fuse box and try and find a relay Retained Accesory Control Module Cannot find exact place but this will set horn off. As for battery car may have key off drain you need to ask speciality shop to do a battery drain test to pinpoint problem. Which in turn may solve all things.
