Welcome to the site. I will move this thread to the Stratus section,

This is what happend to me when my fan would only work on certain settings. Don't know if you have the same problem but this is what I had to go through "Ok so I have kinda the same problem, but I didn't have any problems with heat or cold air. The only problem I had was that the fan would work on #1, the lowest setting, but would sometimes make a grinding sound and would not blow any air out. On monday I had the fan set on #2 and it made the grinding sound, which it never did on any other setting but #1, and then it wouldn't blow any air out on #1 and #2 and only on #3 and #4. So took it in to see what the problem was and it turns out that the resistor and blower motor went out and recric door actuator went out. So we replaced all three for a cost of $500 and as of right now everything works ok." Hope this helps.
