My driver's side door quit working with the power locks or with the factory key-less entry.

Everything appears to be connected.

When you press lock, all the doors lock. The tabs go down and things are great, except on the driver's door. There is not even the pulse in it like it is trying.

Is this common?

Is there anything else that I should check?

How much does it cost to get a new locking motor?

Thanks,
Adrian
