Question about Hummer H3
This work too in other problem in the resistor pack. It internally shorted and burned the
harness. Once you locate the parts it is only like a 30 min fix.
Under the glove box is the blower motor. There is one red plug, that is for the resistor pack. Under that are two screws holding the resistor pack in. Check to see if the red plug is burned, if it is, replace it. Then replace the resistor. The harness to replace also has two other connectors at the blower motor (one for a relay that is beneath the blower motor and one that actually powers the fan). The harness (for an 06 H3) is part 25867517 and the resistor is part 10397098
Note that the motor is a regulated ground don't apply power to this wire; the brown wire is 12V+ and the Orange wire is regulated ground. Here the diagram, visit this LINK.
Hope this helps.
