Do not press the brake pedal when removing or installing the speed control deactivator switch, as the switch will be damaged.
To reinitialize and calibrate the actuator stop points. To carry out calibration, carry out the following steps.
Remove Smart Junction Box (SJB) fuse 15 for at least one minute.
NOTE: When the ignition switch is switched to the ON position, the HVAC module will initialize and calibrate the actuators. Calibration of the actuators will take approximately 30 seconds.
Reinstall SJB fuse 15. Turn the ignition switch to the ON position and wait 30 seconds before verifying correct mode door operation.
