Blower only works on High help?

i have a 94 Nissan Sentra SE on the way to work a few days ago the blower motor stop working. now it only blows on high. do these cars have a blower motor resistor that can be replaced with out replacing a ton of other stuff?
any help would be great! TIA

oh yeah i got this car for free. Wife's best bought a new car and since the starter(50bux) was bad. she didnt want to trade it in.So she told me to come get it. didnt even have to pay the tow (thx AAA)
it has a few dings in it. over all its a clean car. plus all the services have been completed since she first hit the road in 94. i have seen the paper work with my own eyes.

nevermind i used the Search button..... still got the car free though

Same thing just happened to me. Blower Resistor. It's a fuse-type resistor that blows, instead of your blower going boom. Could be other problems that caused it to blow, but you won't know until you replace the resistor.
