One of two things are likely. Fuse blown or the motor has gone out. Fuse box is front left in engine compartment or there is a second fuse box under back seat. Fuse located in one or the other of these, box lid has descriptions of the fuses. If the motor is out, and make sure to check fuses first! it is under and behind the glove box held by a few screws. Prepare to be upside down for awhile. Start with those two things as they are most common. A third option that is less likely, is your control module for the heat and air is bad. Pretty easy fix as well, little more expensive though.

my 1999 winstar was doing this and it was the blend door
under the dash below the glove box
You can unplug the blower motor and run a jumper wire to test the blower motor. If it is grounded through the plug you'll have to run a ground wire to it also. Blower Motor tested good. The Problem was the Blower Motor Controller which was located on the firewall just below the Heater Hoses. Thanks for responses to question.
