Vehicle: 2004 GMC Sierra 3500 8.1 V8 GAS

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 ...
