first of all i am new to this forum and look forward to helping all if i can. i am trying to reset the automatic door locks on my 2000 1500. i have followed the owners manual. it says to pull in the directional and turn the key from off to run twice. then release the directional. doors should lock and unlock and horn should chirp.1= my horn does not chirp. 2=the manual says i have the choice of doors locking at 8mph or when i put the car in drive, or no lock. all i can get is the 8mph or no lock. i cant get the lock when placed in drive option. can anybody help with this. thanks in advance:cheers:

I am not sure this year has the automatic lock, out of park feature.. this is what is says in my service manual for this year:

Vehicles equipped with the automatic door lock option are factory programmed to have the automatic lock feature lock all the doors when the vehicle speed is greater than 15 MPH (24 KM/H) for two seconds, and then unlock all the doors once the key is removed from the ignition. The following instructions detail how to program the automatic door locks. One of the four programming options should be selected prior to entering the programming mode.
To enter the programming mode you need to:

Beginning with the ignition in OFF, pull back on the turn signal/multifunction lever all the way toward you and hold it while you perform the next step. Turn the key to ON and OFF twice. Then, with the key in OFF, release the turn signal/multifunction lever. Once you do this, you will hear the lock switch lock and unlock and a ten second program timer will begin.
You are now ready to program the automatic door locks. Select one of the four programming options listed below. Follow the instructions, then wait for the ten second timer to expire. The programmable auto door locks will now operate in the selected mode. If you were unable to complete the programming in the time allowed, repeat the procedure beginning with step 1.The following is a list of the available programming options:
All doors lock/Driver's door unlocks only: Press the lock side of the power door lock switch on the door panel once, and then the unlock side once.
All doors lock/All doors unlock: Press the lock side of the power door lock switch on the door panel once, and then the unlock side twice (this is the factory setting).
All doors lock/None of the doors unlock: Press the lock side of the power door lock switch on the door panel once, and then the unlock side three times.
No doors lock/None of the doors unlock: Press the lock side of the power door lock switch on the door panel twice. This turns off the automatic door lock feature.

You can exit the program mode at any time by turning the ignition to ON (the locks will automatically lock and unlock to indicate you are leaving the program mode). If the lock/unlock switches are not pressed while in the programming, the respective automatic lock/unlock feature setting will not be modified.
