TSB: Chrysler HVAC Clicking

This bulletin applies to 2024 Chrysler Voyager and Pacifica vehicles built on or before November 19, 2024 and equipped with any of the following:

• 3 zone auto control front/rear A/C
• Air conditioning with 3-zone temp control
• All vehicles with A/C
• Rear air conditioning w/heater

The HVAC recirculation actuator door may repeatedly make a clicking sound after the ignition is turned off. This is caused by a glitch in the HVAC software. Update the HVAC with the latest available software version.
