Chrysler 300 climate control issue with intermittent hot air blowing from all vents despite temperature adjustments and recent sun sensor replacement. on Chrysler 300

Some Chrysler 300 owners report experiencing intermittent hot air blowing from all vents despite adjusting the temperature and replacing the sun sensor. This issue may be linked to a malfunctioning A/C blend door actuator, particularly if ticking sounds are heard, and replacing the actuator (PN 604-004) might resolve the problem. Additionally, some owners find that checking the fuses is crucial, as certain models have power supplied to the body control module that operates the HVAC doors. In cases where the battery has died or been removed, reprogramming the body control module may also be necessary. Promptly addressing these potential causes is important for effectively troubleshooting and resolving climate control issues in the Chrysler 300.
