Air Conditioning Switch (4WD Machines with Operator Cab)
The air conditioning switch is used to turn the air condi-
tioning on and off. When the front of the switch is de-
pressed, air conditioning will be on. When the rear of the
switch is depressed, air conditioning will be off. The air
conditioning switch is located on the cab control panel
(Fig. 42).
Testing
1. Park machine on a level surface, lower cutting deck,
engage parking brake and stop engine.
2. Make sure ignition switch is in the OFF position. Re-
move control panel from cab headliner to gain access to
air conditioning switch.
3. Disconnect machine wire harness electrical connec-
tor from the air conditioning switch.
4. The air conditioning switch terminals are identified in
Figure 43 and the switch circuits are shown in Figure 44.
With the use of a multimeter (ohms setting), the switch
functions may be tested to determine whether continuity
exists between the various terminals for each switch
position. Verify continuity between switch terminals.
5. Replace air conditioning switch if testing determines
that it is faulty.
6. If the air conditioning switch tests correctly and a cir-
cuit problem still exists, check wire harness (see Electri-
cal Schematics and Wire Harness Drawings in Chapter
9 − Foldout Drawings).
7. After testing is complete, connect machine wire har-
ness connector to air conditioning switch. Secure con-
trol panel to cab headliner with removed fasteners.
