1991 suburban blower motor

I have a blower motor that stopped working. I get ohm readings on the switch at the different speeds and I have voltage making it to the switch. I don't think I have voltage at the resistor. Am I trouble shooting this correct or is there another point that could be open?

You have voltage to the switch, but do you have juice on the output side towards the blower? And do the resistance measurements ohms) vary for each setting?
There's a blower motor resistor block that is held in near the actual motor by 2 screws - you should pop that out and make sure it's OK too. If this is the resistor you are indicating may not have any voltage being delivered to it, you may have an open wire from the connector behind the switch over to the blower.
Good luck....
