TROUBLESHOOTING GUIDE
CHECKLIST
• When inspecting the heater or air conditioner, warm up the engine before each operational check.
The engine coolant temperature must be 40 °C {104 °F} or higher.
• The air conditioner is composed of an electrical system as well as a refrigerant system. Because
some refrigerant system components require the evacuation of refrigerant gas before replacement,
inspect the electrical system first.
