Flash: HVAC Performance Enhancements During Remote Start Operation.
This bulletin involves selectively erasing and reprogramming the HVAC Module with new software.
Customers may experience any of the following conditions:
• HVAC system turns off when the driver’s door is opened during remote start operation.
• When display mode is set to Celsius, system may default to full hot during remote start operation.
During Remote Start mode operation, the HVAC system will default to a preselected value of 72°F (22°C) regardless of customer selection or ambient temperature. When the driver’s door is opened, the system will immediately revert back to the previously selected setting. This is a normal operating characteristic.
