Condition
Some customers may comment that the Rear Seat Audio (RSA) or the rear HVAC controls are inoperative. The display will be blank and there is no communication to the RSA/HVAC module.
Cause
A microcontroller was found to lock up causing an "ALDL No ALDL" communication condition. This required the cycling of power by disconnecting/reconnecting the RSA module.
Correction
Replace the RSA module to correct this condition. The RSA module has been updated to eliminate the "HVAC No ALDL" communication concern.
