So I noticed something during the winter/early spring when I was offroading, and wondering if anyone had ever seen this or had any ideas what it might be. After I had been driving/offroading for a while, one of the times I'd turn on the heat, and no matter what it was turned to it came out as window defroster setting. I have a tendency to turn the heat on and off when the top is down and it's a bit more chilly depending on how fast I'm going (and related:how cold the front is). Everytime this happened I would try turning it on and off and fiddling with how strong it was blowing and eventually it would start working correctly. Any ideas?
