Hi guys. I have 97 civic and I have a problem with the door lock, It seem to me there is power but when i open the doors or lock them from outside or inside it dosen't lock all doors it only lock the driver's door.
What would be the problem or how can i fix it?

 

sounds like a possible bad power lock module. you could test it basically by grounding the yellow/red wire on the power lock module and moving the switch to lock. if they lock its definately the module. this is not a fix. if you ground the wire and hit unlock youll blow a fuse.
