it could be the blower relay located in the duct work under the hoodor a blown fuse

If manual system, could be resistor block.....check all fuses first....check power at harness into the resistor block....

Did you check for power at harness to blower motor with a test light or voltmeter? Should use a test light...should get progressively brighter with change in speed....
