check to see if you have good power and ground to the blower motor. the blower motor should be under the dash on the passenger side. It has a two wire plug in. you could run a test light between the two prongs in the blower motor connector and see if the light turns on when you turn the switch for the blower on. Sometimes if bang on the blower motor it will start up. if It still means that you have a bad blower motor but it will work again for a while.
