2005 Vibe - the doors will not lock with the remote or the lock buttons on the doors. However they will still unlock with both the remote and the buttons on the doors. The only way to lock the doors is to manually push the old type manual knobs down on the doors one at a time.
Any clue what is going on here?
I have two of these 2005 Vibes and the other one is still fine with 150,000 miles on it. I can swap parts if you can give me a hint where to start.
