Contour Enthusiasts Group Archives Forums General Troubleshooting Blower fan not working

I noticed the other day that I had the floor heater on pretty warm and on the 3rd fan setting and was not overly warm (by that much time driving, I usually have turned down the temp and the fan setting). I switched it up to floor/panel and put my hand by the vent. Nothing. Just a little warm air leaking out. I switched to the other fan settings...nothing worked EXCEPT the fourth. It still blows like a mother when it's in the highest setting. I have no idea what could be causing this except a bad fan or fan motor...any ideas? Is it difficult to replace??

Thanks!
