Ok so today I tried unlocking my door and then pressing the button again to unlock the other door. I drive a 2000 328ci. The other door unlocked but the driver door did not. However, when I try to unlock the doors while locked, I do hear an unlocking sound comming from the driver door as if something should have been unlocked, but the little pin doesn't pop up and the door remains locked.
The locking switch inside doesnt unlock the door either. the door will lock when you lock the doors, but the only way to unlock the driver door is to pull the handle from the inside.
I figured it could be a lot of things, but hopefully i'm lucky and its only a switch i got to swap out. Can anyone offer any advice. Thanks a lot.
