While a detailed diagnostic procedure for all air conditioning systems would be impractical due to the many variations in construction and operation, there are three fundamental components of a total diagnosis:
- Refrigerant systems must have an adequate, but not excessive charge.
- Determination must be made whether the refrigerant system is governed by a cycling clutch compressor or by valves which control evaporator pressure.
- The air distribution system (blower motor, switches, vacuum lines and air ducts) must be operational before checking the refrigera...

The coolant fan is controlled by the ECM. In the 6 cylinder, the coolant fan is also controlled by the redundant cooling fan switch. When the ECM grounds circuit 335, the coolant fan relay is energized and battery voltage is applied to the coolant fan. If the ECM fails on the 6 cylinder engine, the redundant coolant fan switch will ground the 335 circuit and energize the coolant fan relay. The ECM will ground the coolant fan relay when the coolant temperature sensor indicates the coola...
