Abrupt refrigerant loss due to a 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. 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 HVAC system is divided into 2 separate sections. The first, heating, ventilation and air conditioning, has all procedures that pertain to an HVAC component or function that is not specifically associated with the manual control system. The second, HVAC Systems - Manual, has all procedures specific to the Manual control system.

Begin the system diagnosis with the Diagnostic System Check - Vehicle.

The Diagnostic System Check will provide the identification of the control modules which command the system.

The use of the Diagnostic System Check will identify the correct procedure for diagnosing the system and where the procedure is located.

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-275034-S25464877312007122600000)
  2. «Air Temperature Description and Operation»(ref-275034-S20552414422007122600000)

The Air Delivery Description and Operation contains the following topics

  1. Air speed
  2. Air distribution

The Air Temperature Description and Operation contains the following topics

  1. Heater Mode
  2. A/C Mode
  3. A/C cycle
