SECTION 23A: ACCESSORIES - H3 SERIES
11. WINDSHIELD WIPERS AND
WASHERS
NOTE
When installing a wiper motor, arm or
blade, follow recommended procedures to
prevent misalignment, binding or malfunc-
tion. Check the windshield washer liquid
hoses, fittings and connectors to be sure
they are properly connected and seal with
no restriction to the flow of washer liquid.
Check that wiper arms have the proper
sweep position and the washer nozzles are
aimed so that spray is within the proper
wiper pattern.
The windshield wipers are controlled by two
electric wiper motors that are accessible for
maintenance after raising the appropriate access
panel at the front of the coach (refer to figure 32).
FIGURE 34: WIPER MOTORS LOCATION
Each wiper motor is independently operated:
Depress the upper windshield wiper switch
located on the dashboard L.H. side to the first
position for intermittent wiping, and to the second
position for continuous wiping (Figure 35).
