sounds like a burnt out blower motor resistor
very easy/cheap fix, you should be able to pick one up for less than $20
to remove it
Disconnect and isolate the battery negative cable.
Open the glove box.
Flex both sides of the glove box bin inward near the top far enough for the rubber glove box stop bumpers to clear the sides of the glove box opening, then roll the glove box downward.
Reach through the glove box opening to access and disconnect the instrument panel wire harness connector for the blower motor resistor from the resistor connector receptacle (Blower Motor Resistor).
Reach through the glove box opening to access and disconnect the blower motor pigtail wire connector from the resistor connector receptacle.
Remove the two screws that secure the blower motor resistor to the evaporator housing.
Remove the blower motor resistor from the evaporator housing.
also another thing we had trouble with a van at work once like this the resistor would work for 2 days and quit again, this happened twice
we found out that once the new resistor is installed you have to run the blower at the highest setting for about 5 minutes and start turning it down stopping at each setting for a couple minutes, a light burning odor coming from the vents is normal
(number 1 points to the resistor in the picture below)
