Blower motor not working

Hi, resistor/relay assembly, found a service bulletin, blower runs all the time. Without being being able to check manufacturer specific codes, or do any testing, that is my best guess. That assembly should be located close to blower motor.

Inspect and test the blower motor resistor located -see below

You need to check for power and ground at the blower motor. If ok then the blower motor is no good.

If you look under the dash on the passengers side by the door. Try banging on it with it turned on to see if this will jar it and make it work temporarily
