first problem form the sounds of it im about 95% sure its a window motor, one thing you can try to do is take off the door pannel and tap on the window motor with a screw driver or something of that sort..while holding the button for the window and see if it moves any. if it moves then the motor is sezing* up and needs to be replaced. as for the hatch its hard to say without seeing for myself, have you tried pulling the lever while someone pulls up on the hatch? the cable may be stretch or the lever on the latch itself may be bent or jammed on something. I hope this helps...goodluck
