I'm driving 2003 Accord EX coupe V6 automatic trans.
The problem is that my left door doesn't lock neither by using key lock button or the lock button on the door it self (the one that located on windows control panel and locks both doors). So now I have to do it manually, push the lock switch down in order to lock my baby. Also now I have to use my key to actually unlock her every single time. It is a little bit annoying but my concern is that electronic way doesn't work anymore....

Please if someone knows what it is, suggest me a part number I need to get in order to fix it.

Note it is only for my left door

 

sounds like the connection to the solenoid failed or the solenoid itself failed.

So that part is responsible for distant electronic lock/unlock from key button right? Just making sure that this is what I need
Also I figured out that the picture you providied is probably for 4 doors models because I looked up my assembly for my car and it looks like this
Now the question is do I need 3 or 19? Both have different P/N but is it the same thing?

 

The dif numbers and part numbers would prob be for left/drivers and right/pass side. Before replacing, please test the old one.

 

Well, if you're really lucky that component is OK but the wiring harness has come unplugged or something sillly like that. Check it out.

 

I replaced an actuator and now it work great!!!! PROBLEM SOLVED! THANKS!

 

Glad to hear, thanks for coming back with the "answer".
