So apologies if this is a thread elsewhere, but I couldn't find my specific issue.

My drivers side door locks and unlocks by all methods EXCEPT doesn't lock when I push the manual lock button on the handle. This operation works fine on all the other doors.

I just got the car, my first and it has a problem with the rear passenger drivers side door not unlocking properly ( latch seems to stick ). The dealership agreed to fix this, but then I noticed this additional problem with the divers door during the week. Don't think they are related, I suspect I have 2 separate issues and the problem with the drivers door is the actual door switch ( all all other lock functions work fine )?

Any ideas?
