I drive a 2008 Dodge Grand Caravan. For the past two days I have noticed that when I put my foot on the brake I hear a clinking noice in the passanger side door or it's in the rear passanger sliding side door. It almost sounds as if the automatic lock is locking...but the locks are already locked. I'm not really sure what it is. Would anyone know what is causing this noise... and any help would be greatly appreciated. Also.. when I use my "keyless" entry...the driver side door does not unlock all the time... HELP!!!
