I have a 2007 Honda Accord Coupe. Whenever i press the lock button from the drivers side door, the driver door will lock but will not lock the passenger door. Whenever i press the lock button from the passenger door the driver door will lock but the passenger door still will not lock. I have come to the conclusion that there is something internal wrong with the lock because the switch works for the driver door so there is not a switch issue. I was wondering if a mechanic or someone who has had this same issue would be so kind as to tell me what might be wrong. I really dont want to spend $99 at the local hona dealer to run a diagnostic for them to tell me that a cable is unplugged in the door. Something that simple can be performed from home by my Dad (auto savy). Any tips are appreciated! PLEASE HELP! Thanks
