temperature variation between the left and right hand ducts. Typical concerns may include that the right side of the vehicle cools down but the left stays warm or the opposite. This condition is sometimes associated by the customer with a recent service visit for other non-related repairs. The codes, DTC B0361 or B0441, may be present but will not illuminate a telltale lamp. The HVAC controller unit and the TEMP door actuator motors rely on a feedback system that supplies the controller with count values in order to accurately adjust the air temperature. When battery power is interrupted to the HVAC controller, the current actuator position values are lost. When power is restored, the controller will perform a “sweep test” of the doors from full cold to full hot and record the end values for reference. Over time, the TEMP doors may develop some flexing when run to their extremes. This flexing allows the count values to run out of range (beyond 0-255) and results in DTC code B0361 or B0441 to set. A revised HVAC controller has been released with new programming that allows for a wider tolerance in the expected range of the TEMP door. Replace the controller using the procedure below: Important: On the 1997 Buick Century and Regal, additional steps are required. You will have to run a jumper wire to the new HVAC controller. Be sure to follow the additional 1997 model year steps below. 1. Disconnect the negative battery cable. Important: On the Buick Regal, the console must first be removed to access the HVAC controller. For Buick Century and Oldsmobile Intrigue, skip to Step 10. Apply the parking brake and block wheels. Shift the transmission to first gear. Remove the console trim plate and disconnect the electrical harness. Disconnect the cigarette lighter sockets. Remove the console storage box. Remove the console control plate and disconnect electrical harness for traction control and heated seats, if equipped. 8. Remove the console retaining bolts. 9. Remove the console from the vehicle. 10.Remove the HVAC trim panel, if equipped. 11.Remove the HVAC controller retaining bolts. 12.Disconnect the electrical harness. 13.Discard the HVAC controller.
