Do you have power and ground at the blower motor connector? If you do, more than likely the blower motor died.

There should only be one blower motor. There is one connector plugged into the blower motor and it has two wires. The yellow/black wire should have battery voltage on it with the ignition in the run position. The blue/red wire should have ground with the blower speed selector switch in 1-5 positions.
12 volt test lamp or volt meter should be able to confirm power and ground.

This one happens to have two sets of centrifugal wheels on on top of the other each with its own separate motor I see the harness an there is two exactly the Same I am getting voltage from the supply harness to both how can I check the resistor

Does the blower come on when you have the blower switch on the highest setting?

With the switch on the highest setting the ground circuit for the blower goes directly to ground and bypasses the resistor. If the motor doesn't work on the highest setting and you have power to the blower motor and a path to ground on the other wire. Your blower motor is kaput.
You can also bench test the blower motor to confirm. Usually if you have to beat on the blower to get it to run, the brushes are worn out.
