2008 Mazda CX-9 Sport

Driver's door only opens with key in the door lock while turning and pulling the handle simultaneously.

All other doors function as normal and all door lock switches (even driver) toggle when you press the lock/unlock buttons.

 

did you ever figure this out? Thanks

 

It's been so long, but I believe I had to replace the Door Lock Latch Release.

 

thanks man I wasn’t expecting a reply especially so soon. my girl is having the same issue. Gonna look at it tomorrow!
