Trailblazer HVAC blower

ok guys have an 05 Trailblazer with a HVAC blower (Front) that is not working. I replaced the resistor for it tonight however it still does not fix it. The rear air blows fine but I am told that is in fact a separate blower. This started as a here and there problem and the fan would run on each speed setting 1-5. When the fan was running it didn't make any weird sounds or anything. Now today it wont run or even try to as far as I can tell. So for 250 bucks I can get a new fan speed control do dad or for 160 bucks a new blower motor. ( from GM) So I really don't want to spend 310 bucks if I don't have to. Where should I look next.


Thanks

Well went to Autozone and got a blower motor for half of what GM wanted with a lifetime warranty.. Then I found the problem. I need a new end for the wiring harness that plugs into the resistor for the blower motor. it "sorta" works now, but that should take care of it.
