I had my drivers side window cracked one day and it snowed. unfortunately, some snow fell on my window/automatic lock buttons. Now I cannot lock my door using the automatic door locks on the drivers side or passengers side buttons. My remote wont lock them either. However, the same door buttons work fine to unlock the doors and I can unlock my car remotely. I can lock all my doors at the same time by manually pressing the stem to lock or unlock your doors or of course manually going to each door and locking them. anybody have any ideas what this problem might be? I suspect its the door actuator?
