Wiring Problems of Chrysler Aspen

My four wheel drive automatically engages. Dealer wants me to spend money on parts and are only guessing that those parts will fix the problem. Not once have they checked the wiring. The engagement happens when stationary (unlocking the car). Sometimes when I turn at very low speeds. The lights come one when driving high speed but nothing happens. The following lights turn 4wheel service, electronic stability. I feel it is a wiring problem.
