Has anyone experienced fan performance degradation over time during long drives in humid weather with A/C ON?




Yesterday I started a thread regarding a problem I had with the Air Conditionning after 1 hour 45 min of driving in warm, humid weather.

Symptoms: white mist coming out of A/C vents in central pod + very poor airflow, even at max fan setup. Back to normal later in the day.


My current theory is that the fins of the A/C evaporator got clogged with frost buildup, which melted afterwards.

Anyone to confirm they had similar experience ?

I get the degredation in performance, but no mist. It just seems like a panel in the back moves and cuts off airflow... and then I turn off the air for... oooh, 5 minutes... 10 minutes... open the windows.... and then turn it back on and it performs normally again... and that's about the same time frame mine happens too.

Reassuring to find out it is not unique to my car.

BTW, the mist is very faint. My wife noticed it and pointed out to me. While driving, I would have never noticed it.

My brother had trouble like you are describing with his RT during a trip to FL...he took it to the dealer and the service mgr said there was a TSB...he did the TSB and the problem has not returned..been about 4-5 months....and sorry, I do not know the TSB #...someone may have it here but your dealer should be able to pull it up on his Chrysler program..

On my trip from Florida to Texas a couple weeks ago I was running with the A/C on the entire trip and didn't run into anything like your describing. I found two different TSB's for A/C's http://www.wkjeeps.com/misc/LX/TSB/TSB_2401205a.pdf

I'm guessing the problem your describing fits the first TSB.

Yep . There is a TSB out on this problem for sure. Just had mine flashed yesterday.
