callawassie Report post Posted August 6, 2009 My 2010 FFH has under 2,000 miles on it. Coming back home from first road trip yesterday when the A/C quit working. I live in the South, so it was hot, maybe 94 degrees, and I had been on the interstate for over 3 hours. The wife and I noticed that the cabin was getting warmer, and I kept trying to increase the airflow, the temp, but nothing worked. Almost no air coming out of the vents at all, and certainly not cold air. We were forced to open the windows. I shut the A/C off, and drove for about 15-20 minutes, then when I turned it back on, it seemed to work OK for the rest of the trip. Of course we then drove into an afternoon thunderstorm, so the temp dropped from 94 to 74! Back in the "old days", we would just say that the A/C froze up - does that still happen now? Thing I'll ask the dealer to check it over, but wanted to check with forum readers as well. Thanks for any input or suggestions. Quote Share this post Link to post Share on other sites
lrymal Report post Posted August 6, 2009 Thing I'll ask the dealer to check it over, but wanted to check with forum readers as well. Thanks for any input or suggestions.I thnk this could be a normal occurrence but really should be checked. I have a couple of new window units that are doing that, and was surprised, thinking there would be some sensors... Could be with the high humidity, the conditions were just right for ice forming. We have been hitting 85% humidity at nearly 100 degrees and have had my AC set at 68 degrees. Air flow has been about "medium". I used to keep the temperature at 60 with low air flow, but I thought about ice forming and decided against that combination. Also, I have not been using ''recirculate''. The cabin seems cold with this combo. If the problem just doesn't do it often, I would just add that to a list of any warranty issues and have it serviced at the same time as the first oil change.

Oman Report post Posted August 6, 2009 The FFH has a variable speed electric compressor, so the old logic of setting the temp lower than wanted with a low fan speed is not applicable. You risk coil freeze up and waste power that could be used by the power train. In any case if the air stops flowing then you want the car checked out. Either the coil froze, the fan crapped out, or the controller went out. In any of those cases you need to have it fixed. I get by far the best mileage from a reasonable cabin temp, auto, and recirculate (after the cabin initially cools off). In this mode I get better mileage than having the windows cracked 1 inch.
