I just saw your post & had to reply. I have 95 Beluga Black LWB, in Lafayette but from Slidell. I have had very similar issues, maybe we could trade war stories, haha. After market Viper alarm seemed to be my problem. I absolutely love my baby but I have lost my mind a few times dealing with this truck. But I've also become a **** good mechanic, detective & investigator. I refuse to give in or give up.
