Viewing wiring diagrams an testing electrical circuits with a DVOM - digital volt ohm meter is the way to find the problem . You don't know how to do that ? Your best bet mite be to take to a qualified repair shop.

Your ignition starter is bad.

Try a slim jim first, down the side of the window. Or AAA or locksmith. If no luck, remove the seat first. Find the screws and bolts around the door handle and arm rest. Most Ford's have screws around the outer side of the panel. I don't believe your's does. The panel lifts or pops off. Once the panel is off, you can reach down and open the door. Just a note. I have done some to where the panel came out in pieces.

do you mean 1 of these?

the window regulators may have too much drag. all the windows or just one? after lubing the window regulator and it still drags, the motor for that window will need to be replaced.

timing belt idel spring could be bad

try spraying some WD40 into all the latches including the hatch. the switches have a problem with sticking
