If this is the Manual A/C type, there are two common occurances affecting blower operation.
1st, there is intermittent contact in the blower motor brushes. You can check this by locating the blower motor housing under the dash on the Right Hand side (Passenger Side). With the Ignition Key in the "ON" position, blower switch on "HIGH" firmly slap the housing with your hand. If the motor starts working, there's your problem. If it doesn't, rig up a 12 volt test light bulb and back-probe the connector to the blower motor - Does the light bulb turn ON? If so, then the problem is with the blower motor itself. If it DOESN'T turn on, then the problem is elsewhere (blower relay, blower control switch, or wiring to the motor or from the motor to ground.
