usually what causes that is the blower motor resistor. Get a volt meter and test it according to it's values, 90 percent of the time it's the RESISTOR.

Why would our 97 lesabre blower work sometimes and sometimes not?
If the blower motor randomly and intermittenly quits and does not work, chances are good the blower motor itself is faulty, if the blower motor does not work on all fan speeds from low through high, it most likely needs a blower motor resistor.
