HVAC and Light Issue
This bulletin applies to 2012-2014 Chrysler 300 vehicles equipped with dual zone or triple zone automatic temperature control, or automatic headlamps. The driver and passenger HVAC blower air temperature may not be the same when “Sync” setting mode is selected and the headlamps may always stay on when set to auto mode.
Using a scan tool (wiTECH) with the appropriate diagnostic procedures available in TechCONNECT, verify that all HVAC systems are functioning as designed. Check headlamp function following detailed procedures available in TechCONNECT. If DTCs are present, record and repair as needed before proceeding.
If no issue is found after performing published diagnostics, replace the Sun Load sensor.
