DUAL CLIMATE CONTROL SYSTEM

Chevrolet Silverado

2004 chev silverado, 80000 mi, 5.3l The dual climate control is blowing hot air from the passenger side no matter what the setting. The driver side setting has no effect. I did disconnect the battery previously for 30 min. Any correlation?

You need to use the TECH2 scan tool to perform the HVAC actuator recalibration. If that doesnt work, you might have a bad actuator for the pass side temp door.
