TEST OR INSPECTION
Refrigerant oil leaks out with refrigerant and leaves an oily film that collects dust leaving a
buildup of dirt.
Remove crew cab bench seat and access panel (WP 0501). Visually inspect crew cab
air conditioner hose connections for oil and/or dirt buildup.
If any crew cab air conditioner hose connections have oil and/or dirt buildup,
replace leaking crew cab air conditioner hoses (WP 0216).
