blower isn't getting voltage

Hi my blower motor isn't working and I'm not getting any voltage at the motor is there a way to check the blower motor control processor(i have the auto style control). I took a shot in the dark and changed the ignition switch no luck any help would be greatly appreciated.
Thanks Ryan This is a 2003 gmc envoy with an I6 sorry I didn't put this in earlier

I have no voltage to the blower too. Had a burned out blower and replaced that(wow what a stink). have no voltage at positive wire to blower. Checked fuse, FINE. Relay above blower make contacter type niose and vibration when switched fron med to high speed settings. Where should I go now?

check the blower resistor,try and unplug it the connector is probably burnt .check the end of the connector at the resistor(processor)if the connector is not burnt check for power at resistor connector.

Blower resistor/relay failures are common, replace it.
