1 Abrupt refrigerant loss due to large leak, hose rupture, collision, or pressure relief valve opening. Conditions that allow the refrigerant to seep or bleed off over time do not cause this oil loss. Upon replacement of a component that caused a large refrigerant loss, also add the required amount of oil for the particular component. 2 If more than the specified amount of PAG oil was drained from a component, add the equal amount of oil drained.

Refrigerant System Capacities

The heating, ventilation and air conditioning (HVAC) system is divided into 3 sections. The first, Heating, Ventilation and Air Conditioning, has all procedures that pertain to an HVAC component or function that are not specifically associated with an automatic or manual control system. The 2nd, HVAC Systems - Manual, has all procedures specific to the manual control system. The third, HVAC Systems - Automatic, has all the procedures specific to the automatic control system.

For systems with DTCs, begin the system diagnosis with the following procedure

Refer to Diagnostic System Check - Vehicle .

The Diagnostic System Check will provide the following information

  1. The identification of the control modules which command the system.
  2. The ability of the control modules to communicate through the class 2 or GM LAN serial data circuit.

The use of the Diagnostic System Check will identify and lead the technician to the correct diagnostic procedure.

Review the Description and Operation information to help you determine the correct symptom diagnostic procedure when a malfunction exists. Reviewing the Description and Operation information will also help you determine if the condition described by the customer is normal operation. The HVAC Description and Operation information is divided into

  1. «Air Delivery Description and Operation»(ref-269161-S20188542642007102900000) for the manual system
  2. «Air Temperature Description and Operation»(ref-269161-S05604063442007102900000) for the manual system
  3. «Air Delivery Description and Operation»(ref-269162-S19351399832007102900000) for the automatic system
  4. «Air Temperature Description and Operation»(ref-269162-S33344513542007102900000) for the automatic system

The Air Delivery Description and Operation contains the following topics

  1. HVAC Control Components
  2. Air Speed
  3. Air Distribution
  4. Recirculation Operation
  5. Automatic Operation

The Air Temperature Description and Operation contains the following topics
