With the battery fully charged, disconnect the power lead and see if the battery is dead (or drops a lot of volts) over night. If it dies while disconnected, the battery has an internal short. Then the problem is not the truck. It would be the battery. Check it out.

Checked and replaced all " easy" solutions. This has been a problem ever since i bought the truck. New battery, new alt. new starter, new cables. door ajar lights are always on on the dash, windows and radio work all the time no key needed. obviously wiring just hoping somebody has had same problems and had an answer. im thinking more along the lines of ECM or instrument cluster microprocessor.
