What is your question?
Blower might not work for days, weeks, then might blow for a day or two. New resistor and blower motor. Notice that the blower stops blowing when the ground wire has voltage at the blower motor.
How long has your 2005 Hummer H2 had this problem?
months

Was the resistor wiring connector / pigtail replaced at same time? .. That typically gets damaged as well - have to inspect it very closely - look for blackened terminals / melted plastic on the connector. Connector / pigtail is available.
With all wiring connected - grasp and firmly twist / move the wiring connections for testing - does blower respond?
