on, need to know how to turn them on or what the switch or lever is located
Sucks to be you. Seriously, Who made the chassis for the barge? I have never actually seen a hydraulic wiper system, air and vacuum and electric , yes. Whatever you are looking for has to be within the drivers reach and really should be marked. How many switches do you have to try to find it? If nothing on the dash works to make the wipers go , then you have a power problem. If they are hydraulic, then the engine may need to run, electric wipers will work with just the key on. Have you checked all the fuses? Can you confirm a hydraulic or electric motor by lifting the panels in front of the windshield? These things were trailers on a van frame so they mickey moused as they went and never buried anything
