A/C Blower Not Working

[jizay]

The other day the a/c blower in my 2002 x5 stopped blowing completely. I swapped out my 5 month old FSR with anew one and nothing changed. The aux fan appears to be working. The low side pressure line from the compressor gets cold so i think the compressor is working to but the blower in the car just completely stopped working. Any have an idea of what the output of theFSR shouldbe to theblower motor, or an idea of how to troubleshoot the blower motor? Anyway to check if the aid fan is on the way out even though it appears to be working? No A/C in Florida is unacceptable.
