When I unlock the power lock and open the door on the driver's side on my crew cab it makes a weird swish sound.What is causing this..

Fuel pump priming up. It’s normal.

Yes, fuel pump priming.  Why they didn't quiet it more is a mystery.  Direct injection engines have been out for a while and  on other brands you don't hear the fuel system priming like on our trucks.

Do you hear the noise in the door? if coming from the door, I have no idea.

 

Or do you hear the noise under the bed area? under the bed is the fuel pump priming.
