Have you tried programming, the automatic door lock procedure?
Mode 1, all doors lock when tranny is shifted out of park.
Begin with ignition off. Then pull the turnsignal/multifunction lever toward you and hold it there while you perform the next step. Turn the key to RUN then back to LOCK twice. Then, with the key in lock, release the turn signal/multifunction lever. Once you do this, the doors will lock and unlock, the horn will chirp once, and the 30 second timer will begin. You are now ready to program the automatic door lock feature.
Press the lock side of the power lock switch once. You will hear one, two, or three chimes. The number of chimes tells you which lock mode is currently selected, 1st mode, Continue to press the door lock switch until the number of chimes that you hear matches the nujmber of the mode you want. One chime please. If you take longer than 30 seconds, the locks will automatically lock and unlock and the horn will chirp twice to indicate that you have left the program mode. If this occurs, you can repeat the procedure beginning with step onew to re-enter the programming mode.
You can exit the program mode any time by turning the ignition to run, the doors will automatically lock and unlock and the horn will chirp twice to indicate that you are leaving the program mode. If the lock and unlock switxhes are not pressed while in the programming mode, the current automatic settings will not be modified.
