Not really sure--do you have a factory service manual? You'll have to search around for them--under the hood, dash etc. Is your negative batt. cable tightened?
The loose ground problems were in my T/A so I don't know where they are in the Bonnes.

Found the ground out..it was underneat the seat in the car..I just lifted the carpets today and found the wire was all corroded..now all my seats work and my interior lights stay off...and its not charging irraticly tanks
