Chevrolet Silverado 1500 dual temperature control issue with heat on driver side and cold on passenger side resolved by cleaning grease from temp control module on Chevrolet Silverado 1500

Some Chevrolet Silverado 1500 owners report experiencing dual temperature control issues, where heat blows on the driver's side while cold air comes from the passenger side. This problem may stem from various factors, including a faulty blend door actuator, a blocked A/C system, or an unresponsive control panel. Additionally, some owners have noted that a faulty temperature sensor can lead to inaccurate readings, resulting in incorrect temperature output on one side of the vehicle. To resolve this issue, some owners suggest cleaning grease from the temperature control module, which may help restore proper function. Others recommend recalibrating the HVAC system after disconnecting the battery or performing repairs as a potential quick fix. Addressing these concerns promptly can help ensure effective temperature control in the Chevrolet Silverado 1500.
