Weaver, my Chilton's ran me around $22 in 2002. found it in Detroit at a Murray's. the manual itself covers several chrysler models, INCLUDING the EAGLE. Chilton #20384. J.C. Whitney has a list of manuals in teir catalog, find their site and surf that.
Any auto-parts store can order the above Chilton's for ya, they not normal-stock for shelves.
Re the wiper relay, I really don't know where the damn thing is, if there is one, sorry.
