I finally had enough with the air wipers and changed them to electric from Autex Automotive Devices. The years have not been kind to the old Sprague Devices motors. Upon removal I found that both motors had cracks where the air lines attach to the motors and both were, of course, leaking. From these pictures you can see that these cannot be repaired and they will have to be replaced. If you are having problems of wipers not operating smoothly; not parking; sweeping too far and hitting the windshield edges or just constant hissing under the dash, these may be the problem.

I would like to replace my air wipers to say do not work well. How well do your new electric wipers work? Our coach is a 1990 Regency. I would assume that your old air wipers are the same as my air wipers. Do you have a part number for your electric wipers?

I have electric wipers on my Monarch and am having trouble with over travel on the passenger side. Do your new motors adjust for length of travel.

Try Mill Supply; I got the wiper link parts from them, and that cured the issue.
