TECHNICAL SERVICE BULLETIN: HVAC BLOWER MOTOR CONNECTOR REPLACEMENT - This bulletin provides information to replace the Heating, Ventilation, and Air Conditioning (HVAC) blower motor connector on some 2019-2023MY Forte (BDm) vehicles produced from July 09, 2018 through present, which may experience the air conditioning function inoperative. The blower motor connector pins may have poor pin tension. Poor pin tension occurs when the female pin is slightly open which will not allow for a proper electrical connection. While driving, the road conditions can cause the connector pin to slightly move within the connector and will intermittently contact the male pin. This may cause excessive circuit resistance, causing the blower motor to become inoperative.
