There is one piece missing to the above answer, and it happened to me although on a different vehicle. There are two gas assist struts for operation of the door in addition to the power lift arm. If even one of these assist struts fails, it will cause the motor to labor excessively, causing heat and blowing the fuse. Remember, if a fuse blows, it's for a reason and replacing it will not solve the problem for long. So the problem is likely a compound one.

My suggestion is to remove the lift assist struts one at a time while bracing the door up with a 2x4 or a broom handle or something. If you remove the good one, it will come down on you. If you remove the bad one, it will stay up. You will know it is a bad strut if it does not extend when you remove it from the door. There may even be evidence of failure such as dust collected on the failed strut from leaking oil. Or and oily coating.

In any event, after you find the failed strut replace it, then replace your fuse and you should be back in the business of opening up the rear hatch with the touch of a button.
