My 2010 Chrysler Town and Country Touring makes a loud clicking noise under the passenger side dash board when the A/C starts up. This has been going on for a couple weeks but it would eventually stop and the A/C would work fine. At first putting the A/C in recirculation would prevent the noise from occurring, but now it makes the noise in all settings and speeds. It also does it occasionally when the car is shut down. The A/C would still blow cold air after the noise. I was gone for 2 weeks and didn't use the car. Now the A/C does not blow cold air at all. Any help would be greatly appreciated!

 

Hi amwilson18,
I found a TSB for a whistling sound within the HVAC. I've posted the details in case it is similar to your situation.

TSB NUMBER: 24-005-11
GROUP: Heating & Air Conditioning
DATE: April 02, 2011

SUBJECT: Whistle Sound From Dash While HVAC Is Operating in Floor Mode

OVERVIEW: This bulletin involves replacing the panel mode door link on the HVAC assembly.

MODELS: 2008 - 2011 (RT) Caravan/Town And Country

NOTE: This bulletin applies to vehicles built before April 16, 2011 (MDH 0416XX).

SYMPTOM/CONDITION:
The customer may experience a whistle sound from the dash while the HVAC is operating in floor mode in medium high to high blower speeds.
This condition can happen when the panel door is not closed tightly. The panel door link
has been changed to correct this condition.
