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 ...
