Question type: Maintenance & Repair

When I turn on my climate control system and set it to my preferences the air blows out of the two passenger side vents instead of the driver side vents. Its a dual climate control system/digital climate control.

It could be just low on freon. A low system charge will allow cooling on one side of the evaporator and not the other. If that isn't the issue it could be a broken blend door or the motor that operates the door is bad. You'll need to get up under the dash under the steering wheel to diagnose that.

This is a common gm problem caused by low or no battery voltage (disconnected battery, battery replacement, low or bad battery, corrosion at terminals etc). Go ahead and set the scan tool to erase all codes even if one isn't showing on your tool. This will resolve 99 percent of this type issue. Hvac controller has logic board and loses memory with low/no voltage. It will not work properly till the code is cleared.
