(HVAC) (CONT’D)
Condenser
The condenser should be cleaned with the oil cooler and
the radiator. (See Cleaning on Page 155.)
Air Conditioning Lubrication
Run the air conditioning for about five minutes every
week to lubricate the internal components.
Troubleshooting
If the fan does not run, or the air conditioning does not
turn on, check the fuse. (See Fuse And Relay Location /
Identification on Page 158.) If the air conditioning system
circulates warm air, the refrigerant may need to be
recharged.
