Sorry to hijack but I am having a similar problem. Mine is a 2001 X5 4.4. I have had it for 7 years and on the original FSR. Anyway, yesterday driving home the AC was working great then it sounded like the fan slowed way down and wasnt blowing hard. I could turn the fan all the way up and it would blow harder but air wasnt blowing out much. I could feel that what was blowing out was cold though. This morning driving to work it was the same. Does this sound like I need a FSR? Thanks!!
