SERVICE INFORMATION
Vehicle owners may report the A/C does not turn OFF at times.
Even though the A/C switch is OFF:
- The A/C compressor cycles.
- There is slight idle speed fluctuation.
- The outlet air temperature is cool.
The above conditions may be normal.
There have been HVAC system improvements and design changes.
- These changes affect the way the A/C compressor operates.
- These improvements help reduce window fogging by dehumidifying the air.
For the Applied Vehicles in this bulletin:
- When a defrost mode is selected (either "defrost" or "foot/defrost"),
and
- the outside temperature is more than 36 - 37°F (2 - 3°C),
- the A/C will remain ON with the Mode Control Knob in any mode position, even if the A/C button is OFF. NOTE: The A/C indicator light will not be ON, when the system is operating as described above.
