AC blower

2002 Crown Vick 60,000 miles Auto AC
Yesterday AC blower wouldn\\'t blow. I raised hood and AC lines froze up, so I know AC is running and cooling. I find fuse and check, it is good. Put fuse back in and still can\\'t get blower to blow. Kept messing with control and it started blowing. A time or 2 past couple months this happened except it started blowing by it\\'s self in just a few seconds. Any guesses what might have been problem?

Really common that the resistor for the fan motor fails . It is located in the fan blower box. Held in by a few screws. Plug type connection . Lower the glove box door and you should see it . About the size of a pack of tic-tacs . About 40.00 part.
