2001 Ford Focus Wagon, two problems

When it's cold outside (around freezing temperature) our trunk liftgate won't stay open and instead slowly falls down to close. It's worse the colder it gets.

I'd like to try replacing the supports myself but am unsure how to do it. One end looks easy as there's just a bolt assembly, but the other end is closed in and I don't know how to open or detach it.

Is there a special tool I need? What's the trick?

I can provide a photo if necessary.

The second problem is that the fuse for the rear window wiper keeps blowing. I guess there's some kind of short in the motor. Is that an easy swap or should I get my mechanic to do it?
