I have a 2015 Jetta SE that started having ac problems last year. On long trips in the summer the vents stopped putting out much air. I could have the fan speed on four and could hear it running full speed, but only got a little air out of the vent. I took it to the dealer and they said I had leak in the system and the car shuts down the vents when that happens. They replaced the compressor valve and recharged the system. It was end of summer and I didn't have any more issues until yesterday. It did the same thing as before but prior to doing that the ac did not seem as cold as it should be. Have any of you all had similar issues?
