Windshield Washer/Wiper Switch (Machines with Operator Cab)
The windshield washer/wiper switch controls the opera-
tion of the windshield wiper and washer pump. The
switch is located in the roof console (Fig. 48).
Testing
1. Park the machine on a level surface, lower the cutting
deck, set the parking brake, and shut off the engine.
2. To access the switch, do as follows:
A. Remove the 10 clips, 10 sealing washers, and 10
flangehead screws that secure the roof to the cab
frame, and remove the roof.
B. Remove the console foam.
C. Remove the console panel from the roof console.
3. Disconnect the wire harness electrical connector
from the windshield wiper/washer switch.
4. With the use of a multimeter (ohms setting), test the
switch functions to determine if continuity exists be-
tween the various terminals for each switch position.
Check the continuity between the switch terminals. The
windshield wiper/washer switch terminals are identified
in Figure 49 and the circuitry of the switch is shown in be-
low table:

5. Replace the windshield wiper/washer switch if test-
ing determines that the switch is damaged.
6. If the windshield wiper/washer switch testing is cor-
rect and a circuit problem still exists, check the wire har-
ness; refer to the Chapter 11 Electrical Drawings.
