Some dash lights light - check engine, 4 wheel drive and Stability control and cruise control will not work, sometimes after some heavy rain days or sitting in the sun for 24-48 hours and does not go away. Mechanic tried tracing and code number does not clearly indicate t when tested. Battery went dead to day but test OK - s=not sure if connected to electrical issue, cables are clean on battery & battery is 2 years old.
With all of the lights on and the battery dying, I would suspect something is wrong with the charging system. If the battery is ok, then I would suspect the Alternator. When something is wrong with the charging system, it can make the lights act crazy
^+1. There could also be a problem with the body control module.
