I'm having an issue with the power door locks on my 03 SVTF. When I'm in the car I can lock the doors with the door button but when I press unlock only the passenger door unlocks. This doesn't happen everytime but is becoming more and more frequent. I noticed this when I was using my remote to unlock the car and only the passenger door unlocked. Thought the remote battery was going dead but since it happens with the door switch it couldn't be. Door locks and unlocks with the key just fine. does this sound like the driver side door switch is going bad? any one heard of this problem before? any help is appreciated. thanks.
