OK, i got all the parts i need for the install of the "cap/bolt" but i have no idea how to get the wiper off. i poped the cover off the outside of the wiper and took the 12mm bolt off but i need to know how to take off all the plastic trim pieces on the inside of the hatch...if anyone has any experience doing this help would be appriciated

 

just give it a good pull and it will come right out, the plastic is held in with locking tabs, you really dont need to pull the entire piece off just around the motor area

That is a very helpful set of photos for removing the trim from the hatch. I couldn't figure out which way to pull it off.
