There is a control Module in dash that controls all of the electrical systems. I replaced battery and alternator. Battery would be dead by morn. Took to mechanic and they found that this control module was bad and replaced it. They had to take my truck to dealer to have it programmed. Fixed the problem.

Hi Lardy, That was Body Control Module (BCM) or something different? Thanks. Aka
