The drivers side one has disappeared from our Yeti which is silver.

 

Having had a quick google, they seem to be either left or right.  I presume LEFT would be the same as driver's side?

 

Is it possible to order one already painted?  Cheers

Left and Right are usually as you are sat in the car looking forward.

So the drivers side is the right hand side. 

Do you mean the headlight washer cover?

 

I suspect they are unpainted.

As said usually supplied unpainted, buy two, matching black!
