i need an electrical diagram for my rear wipers and im not talking about my mama. the spray part works just the wiper doesn't. well i have a few other things that don't work but one thing at a time

My past experiences just like this all turned out to be the wiper motor itself. I can dig through my fsm tomorrow and see if i can get the rear diagram for you. You could just start poking aroubd with a test light with the switch in the on position and that will tell you if you have power.

ok i thought it was the wiper motor,how much are new ones?

i found a new one in pullman but it cost about 400 bucks next stop pull and save for a wiper motor.

yea it was the motor,went to pull and save and got a new to me motor and a new to me switch plugged it in and it works. while i was there pulling parts i snagged the rear latch assembly now i don't have to use a bungy cord anymore. now i just meed a new rear bumper the old one got pushed in when it was bumped. the one thing i noticed on the parts car was a black box in the back hatch what was this for?

There's not normally any electronic box in the back of a wagon. I've seen trailer light converters there.
