Question about GMC Sierra 1500
Could be a bleed of for later models or a manufacturer modification so that the same part can be used in different in different vehicle applications
vehicle manufacturers do not make may of the parts in use but use products made by specialist shops and you new unit could fit a range of applications some of which may require that hose connection

SOURCE: Check engine light/code 440?
you should look on the right side of the engine(closest to the firewall) for any loose or disconnected vaccum lines on your intake,throttle body or you evap system. I do have a question? does the vehicle idle rough or does it hesitate on acceleration?

The switch or the wire harness at the blower motor has gone bad. The highest setting 5 has no resistor, so the blower runs on high but the high current flow ends up burning up the switch's contact on that setting or the resistor wire harness at the blower motor has gone bad. Common would be the switch it self, if the switch is good. Then it's going to be the wire leads at the speed resistor by the blower motor under the glove box by the passenger leg compartment. Keep me posted, be glad to help you get your Sierra running 100% again soon.
