SOURCE: I need to remove the

What's the problem? Do you need to know where the screws are, what tool you need to remove the manual crank handle or pry off plastic retainer clips? You remove all the screws you can see including the armrest screws. And either ask for the right tools at a auto parts store or try using a couple of screw drivers. The window cranks are sometimes held on with a screw or nut under a plastic cover on the crank handle, but most use a C clip or wire clip that fits in a groove in the back of the handle between the door pannel and crank.
