Door lock Question
 

I Have an 02,the doors Lock When I Drive away,They Unlock When I Stop,they Unlock When I Push The Lock button To Unlock,But They Won't Lock When I Push Down On The Either Lock Switch Driver Or Pasenger ?

Be sure you are not attempting to lock the doors with the key in the ignition. The system is designed to not lock so as to prevent locking the keys in the car.

If the switches won't work with the key out of the ignition, then I would suspect bad switches.
