I have a 1994 Accord EX 4 door with power locks. For some reason, the power lock on the drivers door will not lock/unlock when the other 3 doors do...The only way to lock/unlock the drivers door is manually by pushing it down or using the key in the door. Likewise, if I insert the key into passenger door, it locks/unlocks all 3 doors, except the drivers door! Any advice??!!

 

Common problem, you'll probably need a new acutator. Use the search feature, it'll probably have all the answers you're lookin for. Good luck
