When I last used the cooled seats on my car last fall, they worked great...they chilled the seats down nice.
Its finally warmer again, and I went to use them last week and the seats barely get cooled now. I stuck my hand under the seats this evening and the fans are blowing warm to ambient temperature. The seat surfaces feel cooler, but not that big of a difference. This is happening with both the driver and passenger side seats.
Only mods are a tune (not sure if that would affect anything) but its kinda odd that its happening with both seats.
