blower motor not working ?

I have a newish blower motor and I recently replaced the resistor as well. It was working although it didn't blow hard
Now the blower motor isn't working at all. The fuse is not blown.
Any assistance in this matter is very much welcome as it is cold outside and I do not want to crawl under the dash without some guidance.
THANKS IN ADVANCE

The steps to isolate the blower motor not working are the same steps you would have used to diagnose the blower or resistor.......or did you just change parts without doing any voltage/ground checks?

If you can’t follow this factory flow chart seek out an auto electric shop in your area.

Your newish blower motor might have failed, of course you should always use a DVM to insure you have voltage and ground on the blower motor leads.
