We just picked up a '99 Expedition. When I was test driving it, and while driving it home, the front A/C was blowing cold, as was the back. Last night while I was messing around with it in the driveway, I had the engine on and the A/C was working in the front, and then it stopped blowing cold air. No matter what I did, such as changing the temp. setting, speed of the fan, etc., nothing would help. Anybody have any idea what is wrong? I sure hope it is just a fuse. Thanks.

Thanks. After doing some searching there, it looks like I very likely have a blend door issue. Great.
