HVAC blower

I had a blown fuse in my hvac blower. I replaced the fuse and still no blower working. It is about 15 degrees and I need heat. I wasn't sure if this required some programming or if thier might be an electrical prpblem with it. Any help would be appreciated.

Thanks

Does the HVAC work on any setting or are they all inop? if it works on say 4 and 5...or only a few settings then its the blower resistor...very common thing to go....

My blower just went as well. I bypassed the switch, to no avail. For me the blower motor was rusty and was freezing when it was cold, hence the not working motor. Check it when the car is warm and see if it works. Could also be a relay which are under the hood closest to the windshield.
