I have this problem from the moment I bought my car. When I push the button on the remote, all doors lock except the front left door. And the same way when I open doors. And there is the same problem when I use driver side toggle switch. I have to use a key every time to open/close driver's door.
I found this topic and now I know that there are 3 possible ways to fix it: replace fuse #8, replace actuator and replace MICU (or relay inside the MICU).
The fuse #8 is OK, and when I winkled it out the toggle switch on the passenger side stopped working. So, now how to figure out what exactly I need to replace: actuator or MICU? Will actuator from another door fit to the driver's door? - Just in case if I will try to check the actuators.

 

have you set the computer to unlock all doors upon lock/unlock? I don't think actuators is the issue

 

Thanks for your reply! But I didn't get your idea.
I had to set the computer to not lock the doors after XX mph, because driver's door never locks and it tries to lock the doors each time after I stop and begin moving again.

 

if only the driver's door is not unlock or locking, then it sounds like the actuator is problematic.

 

Yesterday I removed the lock from the door and connected it to the lock connectors from disassembled passenger's side. It didn't work too. So I think the problem is in the actuator.

 

Yeah lock actuators go bad on these cars. Mine particularly driver side because it’s just me in the car. I’m going on my second replacement in 3 years with oem Honda. 😞

 

Maybe this time you should try third party?

 

As always, try rockauto! Got my actuators from them and they work just fine!
