Hi Troy,
I had the same problems with my 88 several years ago. I don't remember the way the hoses were connected but I replaced both of mine. There are adjustment screws on the wiper motor that you can change the movement process. I moved the screws and put the motor back on with a couple screws and tried it until I had it right.
If you want to get new motors or information from and expert call Rome Truck Parts in Agusta, GA at 706-234-6228. I got new Trico Motors and air switches from them and now have them workling well.
The air operated wipers are the one thing on my Newell that I like the least.
Good luck.
Wally
