rear plugs of 97 GV 3.3

I have a 97 grand voyager 3.3 and have read messages for other vehicle years/models for removing rear plugs. Is removing the wiper cowl for the 97 3.3 the best way to get to them or is there another approach that will not require the removal of numerous components? Thanks in advance.

there are two ways of doing is it, going from underneath the van or you can get it from up top, somewhat narrow, but you can still access them.

I was able to squeeze my hand (1 hand) going from underneath and access them almost blindly. It's a pain to do but it's doable without taking anything apart.
