I've posted various things about Ions numerous times here. I've got a new issue. I've got a 2003 Ion 3, just under 38k. On my way into work yesterday, I turned my heater setting to defog my windshield, put the fan level on 2, and had the temp mid-way through the red side. Then I cranked up my music and welcomed the day. Since the fan was on such a low setting, its normal for me to not hear it running with the music on. Work is about 7 miles from home. I was about a mile out from work when I realized that my windshield was fogging up. I looked down, all the dials were where I left them. I changed to the bi-level heating, and turned the fan up to 4, and realized that the entire time, it had been doing absolutely nothing. I manipulated all the settings, and nothing would make air blow. And than magically the vents started blowing, and have worked fine ever since. (No I didn't have them closed) Has anyone experienced this? Or have any idea what can cause this to happen??
