Hello. have just bought a used '08. had it a week. now all of a sudden neither of the doors on the driver's side will lock or unlock with either the key fobs or the door switches on either driver's or passenger door. the only way to lock or unlock the driver front door is to manually to it with key from the outside, or manually from the inside. only way to luck or unlock the driver's side rear door, is from the inside. have seen other forums this has happened before - but i am not sure what the resolution is. thank you.
