Hi Bandit,
usually it's the battery, the RCM or the central locking pump. Have you measured your battery voltage? Is it above 12V? If you turn your key to on and leave there, do the radiator fans start to go at warp speed. Have you looked under the Styrofoam in back trunk area to see if the CLP/SSM is sitting in water. Have you checked your brake fluid level or looked for signs of rodents chewing up wires in the engine compartment.
Just some suggestions.
