Help! All of a sudden my 1999 2500 club cab 4X4 developed electrical problems. First, I noticed my radio & accessories started going on & off -- with the key out of the ignition. Before I could get it in to the dealership I lost all interior lights/radio/mirrors/and seat belt harness. The dealer has told me I have an electrical problem. If anyone else has had a similar problem I would appreciate any help before the dealership drains me of all funds.
