My corolla has been in my family as long as I can remember. So when I turned 18 it was passed down to me. The only ways to lock and unlock the driver door is to unlock it with the key or pull up on the tab. But when I unlock it from the passenger side. I have to unlock the driver door with a key. So pretty much the power door locks don't work for that door. Except for when I press the unlock or lock button the tab moves a little bit but didn't unlock it. Any ideas on what's causing this?
