I have the same on my 05. Does it inconsistantly. I'll be driving and it will be blowing cold then changes to burning hot. Does this about once a month. I found that if I turn the key off then restart the car on it goes right back to blowing cold. Seems more like an electrical issue than a mechanical I would think. Let me know what you find!!!
