thanks for the help so far. I am guessing that i may have a break in the wiring somewhere, but i havent found it yet. If i erase the codes, The doors lock once when I put the car into gear the first time, but then I have to wait for approx. 30 seconds because I can't get the shifter to go into gear. Then once it allows me to put the car into gear, i have to manually lock or unlock the doors again because the shifter no longer controls that function. I though that maybe a switch in the shifter was malfuntioning causing this. But at this point I don't really know.
